Implemented Nodes using proper Polymorphism
Polymorphic Nodes with Iterators
pi = 3.1415926etc.
Licht transformation umgesetzt
SceneGraph funktioniert
Working with static instances and material injections
Passing objects instead of classobjects in Nodes. Allows instanceof testing. Is not that bad because only one object per iterator is needed (reference is passed).
cleaned up
Added RenderShapes
Again back to using the Class<> Object.

Testing via classreference.isAssignableFrom(Light.class)
This way it's certain, that Light implements/extends classreference.
