Detailed Description
Implements a MeshBuilder that generates a triangular structured mesh.
Mesh generator for a triangular tensor product mesh covering a rectangle.
A triangular tensor product mesh of a rectangular domain is built by subdividing the domain into equal squares and splitting each of them along the diagonal.
The nodes and cells of the resulting mesh are numbered lexicographically from bottom left to top right. The super-diagonal cells have even indices the sub-diagonal cells odd indices.
The horizontal edges are numbered first, the vertical edges next; both groups lexicographically.
