Add toarray to box-geometry so it can be used for only one cube
Add uDiv and vDiv 'pixelspace' divisors to generateBoxesMesh opts (default 64, 64 so that UVs can be written in more convenient units than 0.0 - 1.0)
Add generateBoxesMesh option to set W coordinate of vertex to mesh index (otherwise default 1.0)
Set generateBoxesMesh to use more generic default options, move specifics to avatar.js
Move box-geometry to its own separate module
Update to box-geometry ^0.1.0
