Lots of stuff (Big ones are cam and frame initial features)

There is now a 2D camera in the workspace!
We have a basic 'Frame' definition. It doesn't have any interaction yet...

I started to define spacial math, mostly for doing conversion and getting a grounding on pixel/points/cm reference. The world space is in cm.
