Docstrings missing in WGGraph.py

[alex-pavlides-adarga]

Docstrings missing from functions in WGGraph.py. in particular, the code threw an error running with multi_news after processing a few thousand docs. It has something to do with the function getredundantComponents. But as there is no docstring I don't immediately know what this function is meant to do...Not only do I not know what the function is meant to do, there is also a parameter in there window_size = 4. What does this do and what happens if i change it. Sorry to be difficult but I really want to get your code working nicely.
