- * - * For a fairly comprehensive set of languages see the - * README - * file that came with this source. At a minimum, the lexer should work on a - * number of languages including C and friends, Java, Python, Bash, SQL, HTML, - * XML, CSS, Javascript, and Makefiles. It works passably on Ruby, PHP and Awk - * and a subset of Perl, but, because of commenting conventions, doesn't work on - * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class. - *
- * Usage:
include this source file in an html page via - * {@code } - *
define style rules. See the example page for examples. - *
mark the {@code
} and {@code } tags in your source with
- *    {@code class=prettyprint.}
- *    You can also use the (html deprecated) {@code } tag, but the pretty
- *    printer needs to do more substantial DOM manipulations to support that, so
- *    some css styles may not be preserved.
- * </ol>
- * That's it.  I wanted to keep the API as simple as possible, so there's no
- * need to specify which language the code is in, but if you wish, you can add
- * another class to the {@code <pre>} or {@code <code>} element to specify the
- * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
- * starts with "lang-" followed by a file extension, specifies the file type.
- * See the "lang-*.js" files in this directory for code that implements
- * per-language file handlers.

-    * '<script>foo()<\/script>', which would cause the current decorator to
-    * be called with '<script>' which would not match the same rule since
-    * group 1 must not be empty, so it would be instead styled as PR_TAG by
-    * the generic tag rule.  The handler registered for the 'js' extension would
-    * then be called with 'foo()', and finally, the current decorator would
-    * be called with '<\/script>' which would not match the original rule and
-    * so the generic tag rule would identify it as a tag.
-    *
-    * Pattern must only match prefixes, and if it matches a prefix, then that
-    * match is considered a token with the same style.

-/*
- Class: Canvas
- 
- 	A multi-purpose Canvas Class. This Class can be used with the ExCanvas library to provide
- cross browser Canvas based visualizations.
- 
- Parameters:
- 
- id - The canvas id. This id will be used as prefix for the canvas widget DOM elements ids.
- options - An object containing multiple options such as
- 
- - _injectInto_ This property is _required_ and it specifies the id of the DOM element
- to which the Canvas widget will be appended
- - _width_ The width of the Canvas widget. Default's to 200px
- - _height_ The height of the Canvas widget. Default's to 200px
- - _backgroundColor_ Used for compatibility with IE. The canvas' background color.
- Default's to '#333'
- - _styles_ A hash containing canvas specific style properties such as _fillStyle_ and _strokeStyle_ among others.
- 
- Example:
- 
- Suppose we have this HTML
- 
- (start code xml)
- 	<div id="infovis"></div>
- (end code)
- 
- Now we create a new Canvas instance
- 
- (start code js)
- 	//Create a new canvas instance
- 	var canvas = new Canvas('mycanvas', {
- 		//Where to inject the canvas. Any div container will do.
- 		'injectInto':'infovis',
-		 //width and height for canvas. Default's to 200.
-		 'width': 900,
-		 'height':500,
-		 //Canvas styles
-		 'styles': {
-		 'fillStyle': '#ccddee',
-		 'strokeStyle': '#772277'
-		 }
-	 });
- (end code)
-
- The generated HTML will look like this
- 
- (start code xml)
- <div id="infovis">
- 	<div id="mycanvas" style="position:relative;">
- 	<canvas id="mycanvas-canvas" width=900 height=500
- 	style="position:absolute; top:0; left:0; width:900px; height:500px;" />
- 	<div id="mycanvas-label"
- 	style="overflow:visible; position:absolute; top:0; left:0; width:900px; height:0px">
- 	</div>
- 	</div>
- </div>
- (end code)
- 
- As you can see, the generated HTML consists of a canvas DOM element of id _mycanvas-canvas_ and a div label container
- of id _mycanvas-label_, wrapped in a main div container of id _mycanvas_.
- You can also add a background canvas, for making background drawings.
- This is how the <RGraph> background concentric circles are drawn
- 
- Example:
- 
- (start code js)
- 	//Create a new canvas instance.
- 	var canvas = new Canvas('mycanvas', {
-		//Where to inject the canvas. Any div container will do.
-		'injectInto':'infovis',
-		//width and height for canvas. Default's to 200.
-		'width': 900,
-		'height':500,
-		//Canvas styles
-		'styles': {
-			'fillStyle': '#ccddee',
-			'strokeStyle': '#772277'
-		},
-		//Add a background canvas for plotting
-		//concentric circles.
-		'backgroundCanvas': {
-			//Add Canvas styles for the bck canvas.
-			'styles': {
-				'fillStyle': '#444',
-				'strokeStyle': '#444'
-			},
-			//Add the initialization and plotting functions.
-			'impl': {
-				'init': function() {},
-				'plot': function(canvas, ctx) {
-					var times = 6, d = 100;
-					var pi2 = Math.PI*2;
-					for(var i=1; i<=times; i++) {
-						ctx.beginPath();
-						ctx.arc(0, 0, i * d, 0, pi2, true);
-						ctx.stroke();
-						ctx.closePath();
-					}
-				}
-			}
-		}
-	});
- (end code)
- 
- The _backgroundCanvas_ object contains a canvas _styles_ property and
- an _impl_ key to be used for implementing background canvas specific code.
- 
- The _init_ method is only called once, at the instanciation of the background canvas.
- The _plot_ method is called for plotting a Canvas image.

-
- When a json graph/tree structure is loaded by <Loader.loadJSON>, an internal <Graph> representation is created. 
-
- In most cases you'll be dealing with an already created <Graph> structure, so methods like <Graph.addNode> or <Graph.addAdjacence> won't 
- be of many use. However methods like <Graph.getNode> and <Graph.hasNode> are pretty useful.
-
- <Graph.Util> provides also iterators for <Graphs> and advanced and useful graph operations and methods.
-
- Used by:
-
- <Loader.loadJSON>, <Hypertree>, <RGraph> and <ST>.
-
- Access:
-
- An instance of this class can be accessed by using the _graph_ parameter of a <Hypertree>, <RGraph> or <ST> instance
-
- Example:
-
- (start code js)
-   var st = new ST(canvas, config);
-   st.graph.getNode //or any other <Graph> method.
-   
-   var ht = new Hypertree(canvas, config);

-       Method: morph
-    
-       This method will _morph_ the current visualized graph into the new _json_ representation passed in the method. 
-       
-       Can also perform multiple animations. The _json_ object must at least have the root node in common with the current visualized graph.
-
-       Parameters:
-    
-           json - A json tree or graph structure. See also <Loader.loadJSON>.
-           opt - Animation options. It's an object with optional properties
-          
-          - _type_ Type of the animation. Can be "nothing", "replot", or "fade". Default's "nothing".
-          - _duration_ Duration of the animation in milliseconds. Default's 2000.
-          - _fps_ Frames per second for the animation. Default's 30.
-          - _hideLabels_ Hide labels during the animation. Default's *true*.
-          - _transition_ Transitions defined in the <Animation> class. Default's the default transition option of the 
-          <RGraph>, <Hypertree> or <ST> instance created.
-   
-      Example:
-      (start code js)
-        //json contains a tree or graph structure.
-
-        var rg = new RGraph(canvas, config); //could be new ST or new Hypertree also.
-        rg.op.morph(json, {
-          type: 'fade',
-          duration: 1000,
-          hideLabels: false,
-          transition: Trans.Quart.easeOut

-    /*
-     Method: loadJSON
-    
-     Loads a JSON structure to the visualization. The JSON structure can be a JSON tree or graph structure.
-     
-        A JSON tree or graph structure consists of nodes, each having as properties
-       - _id_ A unique identifier for the node
-       - _name_ A node's name
-       - _data_ The data property contains a hash (i.e {}) where you can store all 
-       the information you want about this node.
-        
-        Hash keys prefixed with a dollar sign (i.e $) have special meaning. I will detail those properties below.
-      
-        For JSON tree structures, there's an extra property _children_ of type Array which contains the node's children.
-      
-      Example:
-
-      (start code js)
-        var json = {  
-            "id": "aUniqueIdentifier",  
-            "name": "usually a nodes name",  
-            "data": {
-                "some key": "some value",
-                "some other key": "some other value"
-             },  
-            "children": [ 'other nodes or empty' ]  
-        };  
-      (end code)
-        
-        JSON Graph structures consist of an array of nodes, each specifying the nodes to which the current node is connected.
-        
-        For JSON Graph structures, the _children_ property is replaced by the _adjacencies_ property.
-        
-        There are two types of Graph structures, _simple_ and _extended_ graph structures.
-        
-        For _simple_ Graph structures, the adjacencies property contains an array of strings, each specifying the 
-        id of the node connected to the main node.
-        
-        Example:
-        
-        (start code js)
-        var json = [  
-            {  
-                "id": "aUniqueIdentifier",  
-                "name": "usually a nodes name",  
-                "data": {
-                    "some key": "some value",
-                    "some other key": "some other value"
-                 },  
-                "adjacencies": ["anotherUniqueIdentifier", "yetAnotherUniqueIdentifier", 'etc']  
-            },
-
-            'other nodes go here...' 
-        ];          
-        (end code)
-        
-        For _extended_ Graph structures, the adjacencies property contains an array of Adjacency objects that have as properties
-        - nodeTo The other node connected by this adjacency.
-        - data A data property, where we can store custom key/value information.
-        
-        Example:
-        
-        (start code js)
-        var json = [  
-            {  
-                "id": "aUniqueIdentifier",  
-                "name": "usually a nodes name",  
-                "data": {
-                    "some key": "some value",
-                    "some other key": "some other value"
-                 },  
-                "adjacencies": [  
-                {  
-                    nodeTo:"aNodeId",  
-                    data: {} //put whatever you want here  
-                },
-                'other adjacencies go here...'  
-            },
-
-            'other nodes go here...' 
-        ];          
-        (end code)
-        
-        Since all visualizations implement this method, this will be the entry point for JSON data for all visualizations. This method could be called like this
-        
-        Example:
-        
-        (start code js)
-        var ht = new Hypertree(canvas, config);
-        ht.loadJSON(json);

-        var rg = new RGraph(canvas, config);
-        rg.loadJSON(json);
-        
-        (end code)
-        
-       Parameters:
-    
-          json - A JSON Tree or Graph structure.
-          i - For Graph structures only. Sets the indexed node as root for the visualization.

- * File: Spacetree.js

- * Implements the <ST> class and other derived classes.
- *
- * Description:
- *
- * The main idea of the spacetree algorithm is to take the most common tree layout, and to expand nodes that are "context-related" .i.e lying on the path between the root node and a selected node. Useful animations to contract and expand nodes are also included.
- *
- * Inspired by:
- *
- * SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation (Catherine Plaisant, Jesse Grosjean, Benjamin B. Bederson)

- * Disclaimer:
- *
- * This visualization was built from scratch, taking only the paper as inspiration, and only shares some features with the Spacetree.

-     Class: ST
-     
-     The main ST class
-
-     Extends:
-
-     <Loader>
-
-     Parameters:
-
-     canvas - A <Canvas> Class
-     config - A configuration/controller object.
-
-     Configuration:
-    
-     The configuration object can have the following properties (all properties are optional and have a default value)
-      
-     *General*
-
-     - _levelsToShow_ Depth of the plotted tree. The plotted tree will be pruned in order to fit the specified depth if constrained=true. Default's 2.
-     - _constrained_ If true, the algorithm will try to plot only the part of the tree that fits the Canvas.
-     - _subtreeOffset_ Separation offset between subtrees. Default's 8.
-     - _siblingOffset_ Separation offset between siblings. Default's 5.
-     - _levelDistance_ Distance between levels. Default's 30.
-     - _orientation_ Sets the orientation layout. Implemented orientations are _left_ (the root node will be placed on the left side of the screen), _top_ (the root node will be placed on top of the screen), _bottom_ and _right_. Default's "left".
-     - _align_ Whether the tree alignment is left, center or right.
-     - _indent_ Used when alignment is left or right and shows an indentation between parent and children. Default's 10.
-     - _withLabels_ Whether the visualization should use/create labels or not. Default's *true*.
-
-     *Node*
-     
-     Customize the visualization nodes' shape, color, and other style properties.
-
-     - _Node_
-
-     This object has as properties
-
-     - _overridable_ Determine whether or not nodes properties can be overriden by a particular node. Default's false.
-
-     If given a JSON tree or graph, a node _data_ property contains properties which are the same as defined here but prefixed with 
-     a dollar sign (i.e $), the node properties will override the global node properties.
-
-     - _type_ Node type (shape). Possible options are "none", "square", "rectangle", "ellipse" and "circle". Default's "rectangle".
-     - _color_ Node color. Default's '#ccb'.
-     - _lineWidth_ Line width. If nodes aren't drawn with strokes then this property won't be of any use. Default's 1.
-     - _height_ Node height. Used for plotting rectangular nodes. _Width_ and _height_ properties are also used as bounding box for nodes of different shapes. 
-     This means that for all shapes you'd have to make sure that the node's shape is contained in the bounding box defined by _width_ and _height_ parameters. Default's 20.
-     - _width_ Node width. Used for plotting rectangular nodes and for calculating a node's bounding box. Default's 90.
-     - _dim_ An extra parameter used by other complex shapes such as square and circle to determine the shape's diameter. 
-     Please notice that even if these complex shapes (square, circle) only use _dim_ for calculating it's diameter property, the complex shape must be 
-     contained in the bounding box calculated with the _width_ and _height_ parameters. Default's 15.
-     - _align_ Defines a node's alignment. Possible values are "center", "left", "right". Default's "center".
-
-     *Edge*
-
-     Customize the visualization edges' shape, color, and other style properties.
-
-     - _Edge_
-
-     This object has as properties
-
-     - _overridable_ Determine whether or not edges properties can be overriden by a particular edge object. Default's false.
-
-     If given a JSON _complex_ graph (defined in <Loader.loadJSON>), an adjacency _data_ property contains properties which are the same as defined here but prefixed with 
-     a dollar sign (i.e $), the adjacency properties will override the global edge properties.
-
-     - _type_ Edge type (shape). Possible options are "none", "line", "quadratic:begin", "quadratic:end", "bezier" and "arrow". Default's "line".
-     - _color_ Edge color. Default's '#ccb'.
-     - _lineWidth_ Line width. If edges aren't drawn with strokes then this property won't be of any use. Default's 1.
-     - _dim_ An extra parameter used by other complex shapes such as quadratic, arrow and bezier to determine the shape's diameter. 
-
-     *Animations*
-
-     - _duration_ Duration of the animation in milliseconds. Default's 700.
-     - _fps_ Frames per second. Default's 25.
-     - _transition_ One of the transitions defined in the <Animation> class. Default's Quart.easeInOut.
-     - _clearCanvas_ Whether to clear canvas on each animation frame or not. Default's true.
-     
-    *Controller options*
-
-    You can also implement controller functions inside the configuration object. This functions are
-    
-    - _onBeforeCompute(node)_ This method is called right before performing all computation and animations to the JIT visualization.
-    - _onAfterCompute()_ This method is triggered right after all animations or computations for the JIT visualizations ended.
-    - _onCreateLabel(domElement, node)_ This method receives the label dom element as first parameter, and the corresponding <Graph.Node> as second parameter. This method will only be called on label creation. Note that a <Graph.Node> is a node from the input tree/graph you provided to the visualization. If you want to know more about what kind of JSON tree/graph format is used to feed the visualizations, you can take a look at <Loader.loadJSON>. This method proves useful when adding events to the labels used by the JIT.
-    - _onPlaceLabel(domElement, node)_ This method receives the label dom element as first parameter and the corresponding <Graph.Node> as second parameter. This method is called each time a label has been placed on the visualization, and thus it allows you to update the labels properties, such as size or position. Note that onPlaceLabel will be triggered after updating the labels positions. That means that, for example, the left and top css properties are already updated to match the nodes positions.
-    - _onBeforePlotNode(node)_ This method is triggered right before plotting a given node. The _node_ parameter is the <Graph.Node> to be plotted. 
-This method is useful for changing a node style right before plotting it.
-    - _onAfterPlotNode(node)_ This method is triggered right after plotting a given node. The _node_ parameter is the <Graph.Node> plotted.
-    - _onBeforePlotLine(adj)_ This method is triggered right before plotting an edge. The _adj_ parameter is a <Graph.Adjacence> object. 
-This method is useful for adding some styles to a particular edge before being plotted.
-    - _onAfterPlotLine(adj)_ This method is triggered right after plotting an edge. The _adj_ parameter is the <Graph.Adjacence> plotted.
-    - _request(nodeId, level, onComplete)_ This method is used for buffering information into the visualization. When clicking on an empty node,
- the visualization will make a request for this node's subtree, specifying a given level for this subtree. Once this request is completed the _onComplete_ 
-object must be called with the given result.
-
-    Example:
-
-    Here goes a complete example. In most cases you won't be forced to implement all properties and methods. In fact, 
-    all configuration properties  have the default value assigned.
-
-    I won't be instanciating a <Canvas> class here. If you want to know more about instanciating a <Canvas> class 
-    please take a look at the <Canvas> class documentation.

- * A radial layout of a tree puts the root node on the center of the canvas, places its children on the first concentric ring away from the root node, its grandchildren on a second concentric ring, and so on...

- * Ka-Ping Yee, Danyel Fisher, Rachna Dhamija and Marti Hearst introduced a very interesting paper called "Animated Exploration of Dynamic Graphs with Radial Layout". In this paper they describe a way to animate a radial layout of a tree with ease-in and ease-out transitions, which make transitions from a graph's state to another easier to understand for the viewer.

-
-     Parameters:
-
-     canvas - A <Canvas> Class
-     config - A configuration/controller object.
-
-     Configuration:
-    
-     The configuration object can have the following properties (all properties are optional and have a default value)
-     
-     *General*
-
-     - _interpolation_ Interpolation type used for animations. Possible options are 'polar' and 'linear'. Default's 'linear'.
-     - _levelDistance_ Distance between a parent node and its children. Default's 100.
-     - _withLabels_ Whether the visualization should use/create labels or not. Default's *true*.
-
-     *Node*
-     
-     Customize the visualization nodes' shape, color, and other style properties.
-
-     - _Node_
-
-     This object has as properties
-
-     - _overridable_ Determine whether or not nodes properties can be overriden by a particular node. Default's false.
-
-     If given a JSON tree or graph, a node _data_ property contains properties which are the same as defined here but prefixed with 
-     a dollar sign (i.e $), the node properties will override the global node properties.
-
-     - _type_ Node type (shape). Possible options are "none", "square", "rectangle", "circle", "triangle", "star". Default's "circle".
-     - _color_ Node color. Default's '#ccb'.
-     - _lineWidth_ Line width. If nodes aren't drawn with strokes then this property won't be of any use. Default's 1.
-     - _height_ Node height. Used for plotting rectangular nodes. Default's 5.
-     - _width_ Node width. Used for plotting rectangular nodes. Default's 5.
-     - _dim_ An extra parameter used by other complex shapes such as square and circle to determine the shape's diameter. Default's 3.
-
-     *Edge*
-
-     Customize the visualization edges' shape, color, and other style properties.
-
-     - _Edge_
-
-     This object has as properties
-
-     - _overridable_ Determine whether or not edges properties can be overriden by a particular edge object. Default's false.
-
-     If given a JSON _complex_ graph (defined in <Loader.loadJSON>), an adjacency _data_ property contains properties which are the same as defined here but prefixed with 
-     a dollar sign (i.e $), the adjacency properties will override the global edge properties.
-
-     - _type_ Edge type (shape). Possible options are "none", "line" and "arrow". Default's "line".
-     - _color_ Edge color. Default's '#ccb'.
-     - _lineWidth_ Line width. If edges aren't drawn with strokes then this property won't be of any use. Default's 1.
-
-     *Animations*
-
-     - _duration_ Duration of the animation in milliseconds. Default's 2500.
-     - _fps_ Frames per second. Default's 40.
-     - _transition_ One of the transitions defined in the <Animation> class. Default's Quart.easeInOut.
-     - _clearCanvas_ Whether to clear canvas on each animation frame or not. Default's true.
-     
-    *Controller options*
-
-    You can also implement controller functions inside the configuration object. This functions are
-    
-    - _onBeforeCompute(node)_ This method is called right before performing all computation and animations to the JIT visualization.
-    - _onAfterCompute()_ This method is triggered right after all animations or computations for the JIT visualizations ended.
-    - _onCreateLabel(domElement, node)_ This method receives the label dom element as first parameter, and the corresponding <Graph.Node> as second parameter. This method will only be called on label creation. Note that a <Graph.Node> is a node from the input tree/graph you provided to the visualization. If you want to know more about what kind of JSON tree/graph format is used to feed the visualizations, you can take a look at <Loader.loadJSON>. This method proves useful when adding events to the labels used by the JIT.
-    - _onPlaceLabel(domElement, node)_ This method receives the label dom element as first parameter and the corresponding <Graph.Node> as second parameter. This method is called each time a label has been placed on the visualization, and thus it allows you to update the labels properties, such as size or position. Note that onPlaceLabel will be triggered after updating the labels positions. That means that, for example, the left and top css properties are already updated to match the nodes positions.
-    - _onBeforePlotNode(node)_ This method is triggered right before plotting a given node. The _node_ parameter is the <Graph.Node> to be plotted. 
-This method is useful for changing a node style right before plotting it.
-    - _onAfterPlotNode(node)_ This method is triggered right after plotting a given node. The _node_ parameter is the <Graph.Node> plotted.
-    - _onBeforePlotLine(adj)_ This method is triggered right before plotting an edge. The _adj_ parameter is a <Graph.Adjacence> object. 
-This method is useful for adding some styles to a particular edge before being plotted.
-    - _onAfterPlotLine(adj)_ This method is triggered right after plotting an edge. The _adj_ parameter is the <Graph.Adjacence> plotted.
-
-    Example:
-
-    Here goes a complete example. In most cases you won't be forced to implement all properties and methods. In fact, 
-    all configuration properties  have the default value assigned.
-
-    I won't be instanciating a <Canvas> class here. If you want to know more about instanciating a <Canvas> class 
-    please take a look at the <Canvas> class documentation.

- * File: Hypertree.js
- * 
- * Implements the <Hypertree> class and other derived classes.
- *
- * Description:
- *
- * A Hyperbolic Tree (HT) is a focus+context information visualization technique used to display large amount of inter-related data. This technique was originally developed at Xerox PARC.
- *
- * The HT algorithm plots a tree in what's called the Poincare Disk model of Hyperbolic Geometry, a kind of non-Euclidean geometry. By doing this, the HT algorithm applies a moebius transformation to the tree in order to display it with a magnifying glass effect.
- *
- * Inspired by:
- *
- * A Focus+Context Technique Based on Hyperbolic Geometry for Visualizing Large Hierarchies (John Lamping, Ramana Rao, and Peter Pirolli).
- *
- * <http://www.cs.tau.ac.il/~asharf/shrek/Projects/HypBrowser/startree-chi95.pdf>
- *
- * Disclaimer:
- *
- * This visualization was built from scratch, taking only the paper as inspiration, and only shares some features with the Hypertree.

-     Extends:
-
-     <Loader>, <AngularWidth>
-
-     Parameters:
-
-     canvas - A <Canvas> Class
-     config - A configuration/controller object.
-
-     Configuration:
-    
-     The configuration object can have the following properties (all properties are optional and have a default value)
-      
-     *General*
-     - _withLabels_ Whether the visualization should use/create labels or not. Default's *true*.
-     
-     *Node*
-     
-     Customize the visualization nodes' shape, color, and other style properties.
-
-     - _Node_
-
-     This object has as properties
-
-     - _overridable_ Determine whether or not nodes properties can be overriden by a particular node. Default's false.
-
-     If given a JSON tree or graph, a node _data_ property contains properties which are the same as defined here but prefixed with 
-     a dollar sign (i.e $), the node properties will override the global node properties.
-
-     - _type_ Node type (shape). Possible options are "none", "square", "rectangle", "circle", "triangle", "star". Default's "circle".
-     - _color_ Node color. Default's '#ccb'.
-     - _lineWidth_ Line width. If nodes aren't drawn with strokes then this property won't be of any use. Default's 1.
-     - _height_ Node height. Used for plotting rectangular nodes. Default's 5.
-     - _width_ Node width. Used for plotting rectangular nodes. Default's 5.
-     - _dim_ An extra parameter used by other complex shapes such as square and circle to determine the shape's diameter. Default's 7.
-     - _transform_ Whether to apply the moebius transformation to the nodes or not. Default's true.
-
-     *Edge*
-
-     Customize the visualization edges' shape, color, and other style properties.
-
-     - _Edge_
-
-     This object has as properties
-
-     - _overridable_ Determine whether or not edges properties can be overriden by a particular edge object. Default's false.
-
-     If given a JSON _complex_ graph (defined in <Loader.loadJSON>), an adjacency _data_ property contains properties which are the same as defined here but prefixed with 
-     a dollar sign (i.e $), the adjacency properties will override the global edge properties.
-
-     - _type_ Edge type (shape). Possible options are "none", "line" and "hyperline". Default's "hyperline".
-     - _color_ Edge color. Default's '#ccb'.
-     - _lineWidth_ Line width. If edges aren't drawn with strokes then this property won't be of any use. Default's 1.
-
-     *Animations*
-
-     - _duration_ Duration of the animation in milliseconds. Default's 1500.
-     - _fps_ Frames per second. Default's 40.
-     - _transition_ One of the transitions defined in the <Animation> class. Default's Quart.easeInOut.
-     - _clearCanvas_ Whether to clear canvas on each animation frame or not. Default's true.
-
-    *Controller options*
-
-    You can also implement controller functions inside the configuration object. This functions are
-    
-    - _onBeforeCompute(node)_ This method is called right before performing all computation and animations to the JIT visualization.
-    - _onAfterCompute()_ This method is triggered right after all animations or computations for the JIT visualizations ended.
-    - _onCreateLabel(domElement, node)_ This method receives the label dom element as first parameter, and the corresponding <Graph.Node> as second parameter. This method will only be called on label creation. Note that a <Graph.Node> is a node from the input tree/graph you provided to the visualization. If you want to know more about what kind of JSON tree/graph format is used to feed the visualizations, you can take a look at <Loader.loadJSON>. This method proves useful when adding events to the labels used by the JIT.
-    - _onPlaceLabel(domElement, node)_ This method receives the label dom element as first parameter and the corresponding <Graph.Node> as second parameter. This method is called each time a label has been placed on the visualization, and thus it allows you to update the labels properties, such as size or position. Note that onPlaceLabel will be triggered after updating the labels positions. That means that, for example, the left and top css properties are already updated to match the nodes positions.
-    - _onBeforePlotNode(node)_ This method is triggered right before plotting a given node. The _node_ parameter is the <Graph.Node> to be plotted. 
-This method is useful for changing a node style right before plotting it.
-    - _onAfterPlotNode(node)_ This method is triggered right after plotting a given node. The _node_ parameter is the <Graph.Node> plotted.
-    - _onBeforePlotLine(adj)_ This method is triggered right before plotting an edge. The _adj_ parameter is a <Graph.Adjacence> object. 
-This method is useful for adding some styles to a particular edge before being plotted.
-    - _onAfterPlotLine(adj)_ This method is triggered right after plotting an edge. The _adj_ parameter is the <Graph.Adjacence> plotted.
-
-    Example:
-
-    Here goes a complete example. In most cases you won't be forced to implement all properties and methods. In fact, 
-    all configuration properties  have the default value assigned.
-
-    I won't be instanciating a <Canvas> class here. If you want to know more about instanciating a <Canvas> class 
-    please take a look at the <Canvas> class documentation.

- * Description:
- *
- * A Treemap is an information visualization technique, proven very useful when displaying large hierarchical structures on a constrained space. The idea behind a Treemap is to describe hierarchical relations as 'containment'. That means that if node B is child of node A, then B 'is contained' in A.

-   Object: TM
-
-  Abstract Treemap object.
-
-   Implemented By:
-    
-    <TM.Squarified>, <TM.Strip> and <TM.SliceAndDice>.
-
-    Description:
-    
-    Implements layout and configuration options inherited by <TM.Squarified>, <TM.Strip> and <TM.SliceAndDice>.
-
-    All Treemap constructors take the same configuration object as parameter.
-
-    Two special _data_ keys are read from the JSON tree structure loaded by <Loader.loadJSON> to calculate 
-    node's color and dimensions. These properties are $area (for nodes dimensions) and $color. Both of these properties are floats.
-
-    This means that the tree structure defined in <Loader.loadJSON> should now look more like this
-
-    (start code js)
-        var json = {  
-            "id": "aUniqueIdentifier",  
-            "name": "usually a nodes name",  
-            "data": {
-                "$area": 33, //some float value
-                "$color": 36, //-optional- some float value
-                "some key": "some value",
-                "some other key": "some other value"
-             },  
-            "children": [ 'other nodes or empty' ]  
-        };  
-    (end code)
-
-    If you want to know more about JSON tree structures and the _data_ property please read <Loader.loadJSON>.
-
-    Configuration:
-
-    *General*
-
-    - _rootId_ The id of the div container where the Treemap will be injected. Default's 'infovis'.
-    - _orientation_ For <TM.Strip> and <TM.SliceAndDice> only. The layout algorithm orientation. Possible values are 'h' or 'v'.
-    - _levelsToShow_ Max depth of the plotted tree. Useful when using the request method.
-    - _addLeftClickHandler_ Add a left click event handler to zoom in the Treemap view when clicking a node. Default's *false*. 
-    - _addRightClickHandler_ Add a right click event handler to zoom out the Treemap view. Default's *false*.
-    - _selectPathOnHover_ If setted to *true* all nodes contained in the path between the hovered node and the root node will have an *in-path* CSS class. Default's *false*.
-
-    *Nodes*
-    
-    There are two kinds of Treemap nodes.
-
-    (see treemapnode.png)
-
-    Inner nodes are nodes having children, like _Pearl Jam_.
-    
-    These nodes are represented by three div elements. A _content_ element, a _head_ element (where the title goes) and a _body_ element, where the children are laid out.
-    
-    (start code xml)
-    <div class="content">
-      <div class="head">Pearl Jam</div>
-      <div class="body">...other nodes here...</div>
-    </div>
-    (end code)
-
-      Leaves are optionally colored nodes laying at the "bottom" of the tree. For example, _Yield_, _Vs._ and _Riot Act_ are leaves.
-
-    These nodes are represented by two div elements. A _content_ element and a wrapped _leaf_ element
-
-    (start code xml)
-    <div class="content">
-      <div class="leaf">Yield</div>
-    </div>
-    (end code)
-
-    There are some configuration properties regarding Treemap nodes
-
-    - _titleHeight_ The height of the title (_head_) div container. Default's 13.
-    - _offset_ The separation offset between the _content_ div element and its contained div(s). Default's 4.
-
-    *Color*
-
-    _Color_ is an object containing as properties
-
-    - _allow_ If *true*, the algorithm will check for the JSON node data _$color_ property to add some color to the Treemap leaves. 
-    This color is calculated by interpolating a node's $color value range with a real RGB color range. 
-    By specifying min|maxValues for the $color property and min|maxColorValues for the RGB counterparts, the visualization is able to 
-    interpolate color values and assign a proper color to the leaf node. Default's *false*.
-    - _minValue_ The minimum value expected for the $color value property. Used for interpolating. Default's -100.
-    - _maxValue_ The maximum value expected for the $color value property. Used for interpolating. Default's 100.
-    - _minColorValue_ A three-element RGB array defining the color to be assigned to the _$color_ having _minValue_ as value. Default's [255, 0, 50].
-    - _maxColorValue_ A three-element RGB array defining the color to be assigned to the _$color_ having _maxValue_ as value. Default's [0, 255, 50].
-
-    *Tips*
-
-    _Tips_ is an object containing as properties
-
-    - _allow_ If *true*, a tooltip will be shown when a node is hovered. The tooltip is a div DOM element having "tip" as CSS class. Default's *false*. 
-    - _offsetX_ An offset added to the current tooltip x-position (which is the same as the current mouse position). Default's 20.
-    - _offsetY_ An offset added to the current tooltip y-position (which is the same as the current mouse position). Default's 20.
-    - _onShow(tooltip, node, isLeaf, domElement)_ Implement this method to change the HTML content of the tooltip when hovering a node.
-    
-    Parameters:
-      tooltip - The tooltip div element.
-      node - The corresponding JSON tree node (See also <Loader.loadJSON>).
-      isLeaf - Whether is a leaf or inner node.
-      domElement - The current hovered DOM element.
-    
-    *Controller options*
-
-    You can also implement controller functions inside the configuration object. These functions are
-    
-    - _onBeforeCompute(node)_ This method is called right before performing all computation and animations to the JIT visualization.
-    - _onAfterCompute()_ This method is triggered right after all animations or computations for the JIT visualizations ended.
-    - _onCreateElement(content, node, isLeaf, elem1, elem2)_ This method is called on each newly created node. 
-    
-    Parameters:
-      content - The div wrapper element with _content_ className.
-      node - The corresponding JSON tree node (See also <Loader.loadJSON>).
-      isLeaf - Whether is a leaf or inner node. If the node's an inner tree node, elem1 and elem2 will become the _head_ and _body_ div elements respectively. 
-      If the node's a _leaf_, then elem1 will become the div leaf element.
-    
-    - _onDestroyElement(content, node, isLeaf, elem1, elem2)_ This method is called before collecting each node. Takes the same parameters as onCreateElement.
-    - _request(nodeId, level, onComplete)_ This method is used for buffering information into the visualization. When clicking on an empty node,
-    the visualization will make a request for this node's subtrees, specifying a given level for this subtree (defined by _levelsToShow_). Once the request is completed, the _onComplete_ 
-object should be called with the given result.
