This file defines several classes of two kind:
There are several flexible general-purpose potential representations, which can take an arbitrary density profile as an input; moreover there are at least two flexible density parametrizations suitable to represent almost anything one may need. If, nevertheless, you want to add a new density model, the necessary steps are summarized below:
