Update Scraper System

Began to update the scrapers to use Node instead of Python both for
speed and ease of deployment.
Old scrapers are in /old system/
Begin changing handleClassPage helpers to closures

In its current state, the UF scraper doesn’t keep track of the previous
class as it should. Switching the helper functions to closures will
allow direct access to the variable without reference.
Updated UF Child Row Scraper

The scraper now properly handles child rows without having to keep
track of references to objects outside of their respective scopes.
