add a new walk sound
send back a 10 level voxel tree from server
print some metrics after voxel send to client
add leavesWrittenToBitstream member variable to VoxelTree for debug
some refactoring in for readCodeColorBufferToTree
add method to repair child masks after adding randomly placed voxels
fix printTreeForDebugging instead of addition of repairChildMasks
Added a utility to VoxelSystem for loading voxels from a local file
Also added a couple shared utility functions for reading command
line options (since that's how you can load a local file at this
point).
1) Added createSphere() to VoxelSystem to create a sphere
2) Added pointToVoxel() to SharedUtils, this will give you a voxel code
   given x,y,z,s,r,g,b
3) Added '.' keyboard interface to create a random sphere in the local
   voxel system
Changed colors of spheres to be a gradient along phi between to random colors
this gives the spheres a little bit more natural look.
Also increased the level of detail (smaller voxels)
