0021336: EDF 1717 SMESH: New algorithm "body fitting" cartesian unstructured

Browse Source 
in initPoly(), do not orient faces of polyhedron as it is just
  wasting time if the user cares him-self of orientation of faces, on the other
  hand the commented code works only for planar faces and convex polyherdons.
