Discrete Mathematics: add new modules for representing graph(network) of various kind and graph operations

[gr8geek]

https://github.com/gr8geek/visma/tree/network-suppourt-added

We intend to create a graph module that could perform various kinds of graph like:
1.weighted graph
2.trees(including balanced binary search tree)
and algorithms:
3.Shortest pathfinder
4.Topological sort
5.Isomorphism checking
6.graph union and intersection
