Implementing functions from toric topology

The aim of this project is to further expand Sage's library for topology, by implementing various functions from toric topology. Though this field might sound specific, a lot of properties can be viewed combinatorially, and that's why they are particularly interesting. These functions are also of interest to researchers in other fields, not just toric topologists. The main idea is to implement as many functions as possible to broaden the library and further make research in this and related areas much easier.
