1) The visitors nested in the SSAPropagationCallGraph have become static classes so that they can be reused in a delegation pattern for the cross-language call graph builder.
2) The ClassHierarchy is now encapsulated behind an IClassHierarchy interface to allow for a CrossLanguageClassHierarchy that delegates to a set of child hierarchies, one for each language. The internals of the ClassHierarchy are almost entirely unchanged
3) There is now a new Language interface in com.ibm.wala.classLoader, and all IClassLoader objects have to know what language they load for. This language object now encapsulates a few language-specific options that were previously hacked into the AnalysisOptions object.
