Basic Constrained Smoothing:  implemented a low memory variant that does not use any additional memory.  However, it came out much slower than the original version and would not be included into this version of BiCal.

EdgeDetector 3D:  greatly reduced the memory requirements.
On BPD_N01 test dataset (from BiCal sample set), the Max Used memory was reduced about x10 times  from 750MB down to 73 MB.  This was done by introducing a specialized simplified function for most common scenarios.  This simplified function avoids generation of the Gradient Map which is extremely memory consuming.

Also, this function is applicable throughout FireVoxel where only the Edge Magnitude map or Binary Edge are sufficient.
