Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

• Separate big codebases into multiple repositories.

This script, when used with Google Apps Scripts, will delete 400 emails and
can be triggered to run every few minutes without user interaction enabling you
to bulk delete email in Gmail without getting the #793 error from Gmail.

Google returns a maximum of 500 email threads in a single API call. 
This script fetches 400 threads in case 500 threads is causing timeouts

Configure the search query in the code below to match the type of emails
you want to delete

/**
* Greedy Algorithm (maximum daily profit from stock sale) - "let me see what my options are, first..."
*
* Overview:
* ---------
* By using Greedy Algorithms we can pass over the data once (O(n) time), storing values we find to be optimal, per our criteria, by
* comparing them to current values. We have to go over the entire set to do this, but we only have to do it once - yay!
* 
* From Wikipedia: "A greedy algorithm is an algorithm that follows the problem solving heuristic of making the locally optimal
* choice at each stage with the hope of finding a global optimum."
