Working on translating current work to use Box2d to handle physics and movement
Further work, TODO: Fix time stepping, needs to call step approx 60 times a second
Physics now scale to meters, camera used to translate to pixels, camera follows main character
Added to the todo list
Experimenting with box2d, added renderer to draw all shapes so collision outlines can be seen
Cleaned up code
Limited player movement speed
Added wall class
Added camera class
Added implicits to help minimize boilerplate
WIP on testability, improved collision resolution
Merge branch 'box2d'
Skeleton weapon code
