* RZBundle
*
* A subclass of NXBundle that provides 2 key features:
*
* \t1\tParsing of the "bundle.table" resource and ability to return key/value pairs
*
* \t2\tParsing of the "class.list" resource and the ability to return the class
* content, protocol conformance and inheritance of objects within the bundle.
