 Problems:
- - Interesting bug - If you make height or width of a component negative. componentColHandle fails to work. 
+ - Fixed: collision detection now works even when a component has a negative height or width.
  - allow objects to skid for componentColHandle()
  - try to delete the obstacle after it goes off screen. right now I just add obstacles forever. 
  - collision handling doesn't work with moving obstacles. currently works by reversing myBox speed. if myBox has no speed, no work.
