32 * Constructor creating object from target cell global number
33 * The constructor first calculates the necessary nodes,

35 * tetrahedra, placing these in the internal vector _tetra.
37 * @param targetMesh mesh containing the target elements
38 * @param srcMesh mesh containing the source elements
39 * @param policy splitting policy to be used
41 * WARNING : in _split attribute, sourceMesh and targetMesh are switched in order to fit intersectCells feature.
