Niccolo',

My strategy is once I am deformation, I convert the mesh back to
Triangle and do all my calculation there. I have also committed
itkTriangletoBinaryMesh a year ago I think which will convert the mesh
to a binary image.

when I have a chance I will check triangletosimplex class to see why it
is using so much memory.
