// Function: createVoxelEditMessage()
// Description: creates an "insert" or "remove" voxel message for a voxel code
// corresponding to the closest voxel which encloses a cube with
// lower corners at x,y,z, having side of length S.
// The input values x,y,z range 0.0 <= v < 1.0
// message should be either 'S' for SET or 'E' for ERASE
//
// IMPORTANT: The buffer is returned to you a buffer which you MUST delete when you are
// done with it.
//
// HACK ATTACK: Well, what if this is larger than the MTU? That's the caller's problem, we
// just truncate the message
//
// Complaints: Brad :)
