/**
* A simple method that returns the value of a + b
* It seems unessesary, but when combined with a reducer it
* adds up all the values in an array.
*
* e.g. `[1, 2, 3, 4, 5].reduce(sum) // => 15`
*
* @param {Float} a
* @param {Float} b
* @example
* // return 15
* [1, 2, 3, 4, 5].reduce(sum);
*
* // returns 6
* Object.values([{a: 1, b: 2, c: 3].reduce(sum);
* @returns {Float} The summed value
