- More code to adapt to the use of heritage and to have multiple scenes.
- Object selection and manipulation is still highly bugged.
- Started adding the new classes that use heritage in the collision
module. This solves the problem that the keyboard commands where
affecting the scene. Fixes #4.
- Started developing the zoom for the collision editor display, not
sure if I will implement this feature for the scene since it needs
to keep the aspect in the operations (eg: you can't move half
pixel).
- I need to split the collision module in submodules as it has too
many classes and most of them don't affect each other.
