Parse a header string to a key-value format wrapped in an Array

parseHeaderString.js

/*
    @description  A function that takes in some headers as a string containing newlines. 
                  It will split the string on its newlines, and then will split it into
                  a key-value pair for easy deploying into HTML.

    @param headerStr [String]
    @returns headers [Array]
