* \brief Compute the signed distance from a N-dimensional sphere.
*
* A instance of sphere is defined by a set parameters. The first parameter
* is the radius and the next SpaceDimension parameters represent the center.
* The first parameter forms the set of ShapeParameters and the remaining
* parameters the set of PoseParameters.
*
* This class is templated over the coordinate representation type
* (e.g. float or double) and the space dimension.
