Flow independent

I have now changed the functioning of the SETSe package so it is totally flow independent. This is an important change as the algorithm was originally designed for flow networks and the running of SETSe required flow and edge capacity data. As the algorithm is not actually a flow algo, this has been removed to allow for easier use with all network types, including binary unweighted networks.
