Solve a system of polynomial equations using homotopy continuation methods. (See
track for more optional arguments.)
The system is assumed to be square (number of equations = number of variables) and to have finitely many solutions.

The output (produced by
track with default options) contains all
points obtained at the end of homotopy paths when tracking starting at the
totalDegreeStartSystem. In particular, this means that solving a system that has fewer than Bezout bound many solutions will produce points that are not marked as regular. See
track for detailed examples.
