This file contains general utility for polling google sheets.
Note that it is not used for the REQUISITION of the service,
as that is in the domain of GoogleApi.py.

It is instead for more general things, like parsing a sheet into 2d array,
etc.
My goal is to abstract all of the sheets bullshit out, and make reading
from a sheet as easy as working with a 2d array, as well as making it
fairly fast.
