Added a function to import departments from the OpenDataV2 data

Modified import courses and departments to use OpenDataV2. Need to test

Removed old code, now solely uses OpenData V2. Needs review

Removed all opendata2 json files except for cs do that the diff size is manageable

Load all data points for a particular course including prereqs and antireqs

Added get_departments() as a function in crawler.py

Moving all functions to crawler.py, need to update aggregator
Added an update_course() function to aggregator.py, so it can be called independently of other code

Added functions to aggregator.py, will now be called daily as part of an existing cronjob

Fixed quotes

Added a trailing newline

Followed David's advice for cleaning up code

Removed idx variable so that courses are always either updated or added

Courses now are updated rather than skipped over
Removed testing folder
