<P>
Utility class to handle reflection on java objects.
Its main purpose is to allow ant-contrib classes
to compile under ant1.5 but allow the classes to
use ant1.6 classes and code if present.
The class is a holder class for an object and
uses java reflection to call methods on the objects.
If things go wrong, BuildExceptions are thrown.
