[Jelly] BCEL Taglibrary applied changes

[Mark R. Diggory]

Thaks everyone for all the great ideas. I've applied many of the changes suggested in the list. I've also moved the taglibrary into the org.apache.commons.jelly.tags.bcel namespace for future inclusion into the Jelly taglibraries CVS tree. First however, I want to expand upon the Class Extender to attempt to apply some of the ideas that Jouzas suggested in relation to BSF.

The new syntax is outlined in the attached model.xml file.
