/**
 * Returns a copy of the array, sorted according to the comparator function,
 * which should accept two values at a time and return a negative number if the
 * first value is smaller, a positive number if it's larger, and zero if they
 * are equal. Please note that this is a **copy** of the list. It does not
 * modify the original.
 *
 * @param {Function} comparator A sorting function
 * @param {Array} arr The list to sort
 * @return {Array} a new array with its elements sorted by the comparator function.
 * @example
 *
 *      var diff = function(a, b) { return a - b; };
 *      sort(diff, [4,2,7,5]); //=> [2, 4, 5, 7]
