[Soot-list] Creating mutants in Java classes

[Guru Devanla]

Thanks Marc-André! I have started work on this. I will try to make this
generic so as to submit a PR.  Is there a similar method that gives "all
references" in the set of classes to a particular member attribute. I
understand I could loop around and figure this out. But, I thought I could
use one if it is part of the framework.

Thanks
Guru
