* This method is part of the Slice3D algorithm. It is the second step of assembly process, ones coordinates have been computed (by MEDCouplingUMesh::split3DCurveWithPlane method).
* This method allows to compute given the result of 3D surf cells with plane and the descending connectivity 3D->3DSurf to deduce the intersection of each 3D cells
* with a plane. The result will be put in 'nodalRes' 'nodalResIndx' and 'cellIds' out parameters.
