removed the article crud module
Bootstrapped Club and Player data models

Created a /reset API endpoint that drops the Club and Player collections
from MongoDB and defines the indexes for both collections, before going
on to pre-fill the database with dummy data (to be replaced in the
future with actual data)
Added authorization check for /reset endpoint

DB reset can only be triggered by users with admin priviledges
Flatten data model object

Flattened the data model object structure to liaise better with the
ngGrid implementation in the view
Add ngGrid

Added ngGrid from angular-ui to display tabulated data with sort and
filter capabilities on the Market page
Replace ngGrid with angular-datatables

ngGrid sucks! It also looks like shit! Swapped it out real quick for
angular-datatables which offers more fine control over appearance and
functionality as well as options
Added populate code to Player data model

This tells the Player model to pull along the Club and User models that
the player references whenever query request any Player from the DB
