-- Make a whole new class for each model called "Player", "DbUser", etc. and wrap mongoose completely.
-- Create a corresponding namespace "PlayerCollection", "DbUserCollection", etc. for the database model itself and its
-corresponding methods.
 - Decide on whether to always use the namespace to call methods and pass an id, with the returned objects "Player",
 "DbUser", etc. all being immutable object copies with limited attributes and no methods, or actually create extra
 classes that have methods that can be called (right now thinking the first idea is better).
