Define and compute with generalized spherical distributions - multivariate probability laws that are specified by a star shaped contour (directional behavior) and a radial component.

Generalized spherical distribution definition, density, simulation
Define a generalized spherical distribution by specifying a contour function, a radial density function, a radial simulation function, and a value of the density at the origin. Once it is defined, compute density and simulate that distribution.
The directional part of a generalized spherical distribution is defined by a contour function, cfunc for short. These functions are used to define a contour function and then evaluate it.
