TreeWizard is my first attempt at a utility class that lets you create and navigate trees without relying on an ANTLR grammar. You will find it attached with about 30 unit tests. This is only my development branch so we are free to update, change, and otherwise mangle the definition. I just want to make sure that we have something out there that people can try out to make sure I'm going in the right direction. See the unit tests for more examples than I give here. Also note that I think I changed CommonTree's getText to not call toString(), but call getText():

Creating trees
Creating a tree is a simple matter of supplying a pattern for the tree using the token names from an ANTLR grammar:

Tree Equality
If you want to compare to two trees, you'd have to write your own method to do so right now. The equals() method in Java is not necessarily the right way to implement either because that is probably just matching to nodes not trees. The TreeWizard provides a method to check the equality two trees (one static and one instance method):
