[Soot-list] use soot in new eclipse plugin

[Jian Xu]

Hi Eric:
Thank you very much for your repaly! Can I ask some question, as follows:
1: under what condition, the Scene.v().setSootClassPath() API can work? And
if it work, which help it can give us?
2: when soot resolve or load class, are there some magic or special thing?
