 The main two "packages" are intended for:
 
 - superelliptic curves,
 - $(\mathbb Z/p)^n$-covers of superelliptic curves.

 There are three auxilliary classes: superelliptic_function (for functions defined on superelliptic curves), superelliptic_form (for forms defined on superelliptic curves) and superelliptic_cech (for cech cocycles for the de Rham cohomology on superelliptic curves).
