Added geometric primitive aggregator
Moved sphere over to Vertex_PC
Added to_str to vectors
Added more primitives for voxelization
3D grid of voxels is being created
Added image of initial voxel grid
Added wireframe rendering and fixed camera view
Rendering sphere with grid
Sphere showing in grid
Moved sphere to Triangles and cleaned up
Added index-based rendering for voxels

Right now, voxels are still hacked into sphere. This will
need to be changed very soon for there to be a new voxelmap type
which will hold the vertex and index data.
Refactored voxel work to new voxel modules
Merged in vox
