reduced memory footprint of marching_cubes #7

memory size_t *shared_indices was the memory limiting var in marching_cubes and took 24byte per voxel while rendering the mesh. Since the var is only needed for i and (i - 1) while processing in x dimension, the x dimension is removable, see usage of i_mod_2 and i_mod_2_inv
