Detailed Description

Implements a MeshBuilder for a tensor product grid of a torus.

The torus is built from a tensor product mesh covering a rectangle with opposite sides identified. The major radius of the torus is proportional to the rectangle's width (x-axis), the minor radius is proportional to the rectangle's height (y-axis). The parametrization is described here: https://en.wikipedia.org/wiki/Torus#Geometry
