// ShpTet10.h  -   this file contains methods for the 10-noded quadratic
//                 tetrahedron solid finite element shape.
// -------------------------------------------------------------------------
// Remarks:
// -------------------------------------------------------------------------
//
//      The nodes are numbered according to the following rule:
//      1.  first, counterclockwise, the nodes at the face with
//          natural coordinate L4 = 0,
//      2.  then, also counterclockwise, the nodes at the middle
//          of the edges that go from the node with L4 = 1 to the
//          the face with L4 = 0,
//      3.  and finally the node at the vertice with L4 = 1.
