Data intake

[jamieRollison]

We need to be able to intake data and store it as a graph somehow. This issue also involves data correction: we should probably parse the data and replace url encoding with readable text. The parsing functions given to us in mp_schedule may be helpful here.

I believe all this should go in the Wikigraph file constructor (branch: wiki-constructor). We will need:

• [x] Open the file.
• [x] Iterate over the data.
• [x] Clean the data: Decode URL Encoded article titles.
• [x] Insert each article into the map.

Those parsing helpful functions will be useful. Let's adapt those and include them in utilities.cc / utilities.hpp

We seem to have reached all the goals, so I'm marking this issue as closed. Great work!
