[Improvement] C/C++ shared/static library interface

[CharlesJQuarra]

I was hoping to use this library to integrate polynomial functions over polytopes inside a c++ application, so I tried to browse inside the drivers that have a main(), It seems these drivers have a lot of logic inside them and is not straightforward how to call the top-level functionality from c/c++.

I considered using execve but it doesn't seem justified to resort to this given this is not a closed binary. I wonder if there are some guidelines for perhaps building a V-representation object in code and pass that to an integrate call
