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.
