cascade L
Given a list of generators of an ideal I, this function creates an embedding and then runs a cascade of homotopies. The output is a NumericalVariety that contains a WitnessSet for each pure dimensional variety contained in V(I).

Coefficient ring of the polynomial system must be of type ComplexField.
The object cascade is a method function with options.
