- Changed directory structure significantly, moving gfx api implementations to fennec/renderers

- Began new overarching window interface
 - Began outlining renderer interfaces
 - Began a binary tree implementation in bintree.h, this will act as a generalized binary tree, then red-black tree will be implemented on top of it for sequences (ordered sets)

   This will allow us to sort objects as they are created. We can still bulk render each z-index,
