Detailed Description

Utility hash function (struct) for custom typedefs.

Note

This struct is necessary because an std pair is not a primitive datatype. This means that we have to provide a custom hash function for the unordered containers (both map and set). See: https://stackoverflow.com/questions/15160889/how-can-i-make-an-unordered-set-of-pairs-of-integers-in-c. Could also use std functions as a solution.
