Implementing real polyhedral homotopy

We implement a real polyhedral homotopy method using three functions.The first function provides a certificate that our real polyhedral homotopy is applicable to a given system; and the second function generates binomial systems for a start system; and the third function outputs target solutions from the start system obtained by the second function.This work realizes the theoretical contributions in [8] as easy-to-use functions, allowing for further investigation into real homotopy algorithms.
