public class TransformingTreebank
This class wraps another Treebank, and will vend trees that have been through
a TreeTransformer. You can access them via requests like apply()
or
iterator()
.
Important note: This class will only function properly if the TreeTransformer used is a function (which doesn't change its argument) rather than if it is a TreeMunger.

Compatibility note: Until Sep 2004, this used to create a Treebank
with a SimpleTreeReaderFactory, but this was changed as the old
default wasn't very useful, especially to naive users.
