[Soot-list] Class Hierarchy with no entry point - catch 22?

[Marc-Andre Laverdiere-Papineau]

Hello,

I just tried the exact same code with the nightly build and there were 
no changes.

I do understand that, conceptually, a call graph needs a starting point, 
and so does an interprocedural flow. But I just want a class hierarchy 
here :)

Maybe it would be a good idea to refactor cg.cha into a separate pack?
