Support 2D array inputs for WIKIDATAQID.

This is related to #41

This is the first PR for broad support for your Wikipedia functions to support array inputs.

• Example usage: ==WIKIDATAQID(A6:A10).
• Example spreadsheet: https://docs.google.com/spreadsheets/d/10pFViQJSXBN6lbryWmB2xG4EkggKdGkyzn3NLKXVEnk/edit#gid=0

The goal of this PR is to establish a baseline for how we'd like each function to be updated, and then update many more.

FYI, this is my first ever pull request :)

I'm trying to merge the first 2 commits into one, but this is confusing. Starting the PR over.
