- playing around with marching cubes (note - terrain is broken currently)
- fixed some marching cubes stuff (need to play around with normals I think)
- working on marching cubes alrogithm (seems like the normals are not working right...)
- added nussubg voxel shaders
- fixed issue with lighting in voxel shaders (won't be visible to git, as the files were just added to the repo)
- fixed issue with voxel shader (not using material data)
- got basic marching cubes (with normals) working...could still use a bit of work, but the basics work
- some cleanup
