Explore use of Commons SCXML for dialogs

Description

Based on dev list discussions, it will be worthwhile to explore the possibility of using Commons SCXML for the internals of Shale dialogs. Additionally, supporting the use of SCXML documents to describe Shale dialogs also has numerous advantages. A starting point for this work is available here:

 http://jakarta.apache.org/commons/scxml/usecases/scxml-in-shale-dialogs.html

Now that we've had a Commons SCXML release and discussions about Shale dialogs have begun afresh, its a good time to add this request as a JIRA ticket.

An example stylesheet that may be used to convert dialog-config.xml (logical name) files to SCXML documents. Might be useful for porting existing config files if shale-dialog2-scxml comes out of sandbox.

Also see this module in the Shale repository sandbox for the latest (experimental, unreleased) code related to this issue:

http://svn.apache.org/repos/asf/shale/sandbox/shale-dialog2-scxml/

[Rahul Akolkar]

Patch that fills up some of the holes in the shale-dialog2-scxml module in sandbox (patch created from module root directory). Patch contains three new files and modifies two existing files.

Completely untested (in the sandbox spirit) but should be close to being functional.

I've committed the basic implementation classes in SHALE-263-01.diff.

[Rahul Akolkar]

Filled in the missing bits in the shale-dialog2-scxml module, and added shale-test-dialog2-scxml app.

Marking as fixed since we're beyond the exploration stage -- a functional module stemming from this ticket (shale-dialog-scxml) is available in framework trunk.
