Add a velocity dispersion function sampler to skypy, which is describes the populations of lenses in sigma_v space. Sigma_v is velocity dispersion of the lens. The equation used for this is found in Choi et al. (2017). The paper uses data of Elliptical galaxies from the Sloan Digital Sky survey.
Inputs
Minimum sigma_v, maximum sigma_v, resolution of function, size (number of samples to be returned)
