Description

proposed improvements:

• introduce TreeFactory.createReadOnlyTree(Tree readOnlyParent, String childName, NodeState childState) in order to reduce dependencies to internal ImmutableTree
• introduce TreeLocation.getName()
• introduce constants for path and name of the root tree

furthermore in the implementations:

• use root-node related constants in ImmutableTree
• simplify ImmutableTree.isRoot
• remove redundant checks for null when param is marked nonnull
• add missing param annotations
