## Detailed Description

### template<const int dim> class WFMath::Ball< dim >

A dim dimensional ball.
This class implements the full shape interface, as described in the fake class **Shape**.

This class is called Ball<> instead of Sphere to be more in tune with the usual mathematical naming conventions, where a ball is a filled object, while a sphere is just the outer shell. It also helps that a Ball<n> corresponds to an n-ball, while a Sphere<n> would correspond to an (n-1)-sphere.
