       SurfaceBasedSmoothing - part of ANTS registration suite


       usage :
              SurfaceBasedSmoothing      ImageToSmooth       sigma      SurfaceImage      outname

              We assume the SurfaceImage has a label == 1 that defines the surface sigma  defines
              the geodesic n-hood radius --- numrepeats allows one to use a small geodesic n-hood
              repeatedly applied many times -- faster computation, same effect
