Proof of concept for providing networkx functionality as REST API.
This is not safe nor intended for production use. Reflection is used to import and execute the right function and could very easily be misused.
NetworkX implements a lot of graph algorithms, some of which are very difficult to implement. By setting up this NetworkX server, we can use those algorithms easily when not working in Python.
A GET request to `localhost:5000/nx/{nx_function_name}' returns the documentation page of that function.
A POST request, where the body contains a kwargs like JSON, will run the requested function and return the result.
Graps in the input should be given in node_link format, and is only supported for parameters named G.
Functions that modify or output the graph are not currently supported.
