Detailed Description

The SymCosMesh class represents a symmetric cosine mesh. The mesh points are spaced such that when the mesh is used to subdivide a spherical volume into conical slices by polar inclination angle $0\le \theta \le \pi$, the resulting slices have equal volume. Specifically, the mesh is contructed as follows:

• construct an equidistant linear mesh over the (inverted) interval $[1,-1]$ with the requested number of bins;
• replace each mesh point by the arc-cosine of its value, resulting in a mesh with the intended spacing over the interval $[0,\pi ]$;
• divide each mesh point by $\pi$, rescaling the mesh to the unit interval $[0,1]$.

The scaling in the latter step is required to conform to the standards for all Mesh classes. When the mesh is actually used to discretize an inclination angle, it will be scaled back to the range $[0,\pi ]$.
