Added subcategory link scrape to script. Script now accesses base category pages and scrapes for relevant subcategory links. Uses site structure and special <li> object to determine when all relevant links have been accessed.

Added .csv duplicate entry checking. Script now checks for an entry before saving a new copy to the database. This currently reads the entire contents of the .csv to a list, and modifies the list in addition to the .csv. Probably inefficient, search for a better way to get that done.

Added new function to remove 'in LOCATION LOCATION' parts of title strings from entries.
