Create a 3D->2D projector #17

Add a method to the object class that projects the 3D vertices to 2D screen coordinates. This method should be defined in scene.cpp and should return an std::vector<std::array<Position2D, 3>> with the vector length being the same as object.vertices.size().

Progress on this issue:

[x] 2D matrix rotation - e8410c12c017f316cbe513c226d799070349b769 2h48m
[x] 3D coordinates to 2D screen coordinates - 7cb4999af8406c5a1189eb07eb7a464e7bb743e2 1h20m
[x] 3D rotation - 18592f85ee4fbf1d729547657b1a6c7690224122 2h40m
[x] Camera rotation - ef719774dfc08bfdfc5b1b5f31ae1cfd4982086d 49m
[x] C++ implementation - 47468327e131bfb4a985a7b536c596ef5c6f2b24 4h47m

Total time spent on this: 12h27m

I'll add more items to this checklist if necessary

@amieleg I need a draw loop in order to implement the above in c++. Here's how it's done in js: https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame

Waiting for mainloop-window merge to dev for 3d-projector-cpp merge to dev, then dev to master
