[Soot-list] Instrumentation of a class

[Eric Bodden]

Hi Ken.

As far as I can see, you could add those fields to just any class,
couldn't you? So why not just generate a new, fresh SootClass, and add
the fields to that class instead of trying to use some "main" class
that does not exist? Could that work for you?
