Detailed Description

Tools to define a BoundaryMesh and use it to generate a BezierMesh.

This class provides tools to use when designing a new mesh from scratch.

Most of the real work is done in the ConformalMesher (to create a conformal mesh) and the BezierMesh (to refine it). What the MeshConstructor does is correctly stage this work, and translate various shapes into splines.
