[Soot-list] How to do several passes over the code

[David Mohr]

Hi Eric,
thanks for the very quick response!

After your suggestion I tried using a SceneTransformer, but that
requires using whole program mode. Whole program mode is not necessary
for my purposes, and it also resulted in some issues resolving
classes, which I didn't have before.

I ended up adding the field to classes on demand, which seems to work
well. I guess I didn't want this "extra" logic before, but in the end
it was easier to implement than dealing with the issues in
whole-program mode.
