-Split bi-quadratic into linear
-******************************
-
-This functionality allows to split bi-quadratic elements into
-linear ones without creation of additional nodes.
-
-So that
-
-* bi-quadratic triangle will be split into 3 linear quadrangles;
-* bi-quadratic quadrangle will be split into 4 linear quadrangles;
-* tri-quadratic hexahedron will be split into 8 linear hexahedra;
-* quadratic segments adjacent to the split bi-quadratic element will be split into 2 linear segments.
