/*
Fireworks CS5 JavaScript Command
Cuts multiple overlapping paths into individual pieces, like Divide Paths in other vector apps

BUGS:
- If one path is entirely contained by another path (such as a donut), resulting paths are
  unexpectedly split apart because we use split paths to reverse the effects of joining. 
  Such results can be manually fixed easily and this method is way more reliable than v1, 
  so we live with it.
