differenceWith function. Performs two arrays difference

differenceWith.js

/**
 * Filter out element from excludeFrom array if it equals
 * to some of the elements in valuesToExclude array
 * Inspired by lodash differenceWith
 *
 * @param {Array} excludeFrom array to exclude from
 * @param {Array} valuesToExclude values which we need to exclude from first array
 * @param {Function} comparator returns true if two elements are equal
 * @returns {Array} Returns the new array.
 * @example
 *
 * differenceWith(
 *    [{ 'x': 1}, { 'x': 2 }],
 *    [{ 'x': 1 }],
 *    (a, b) => a.x === b.x
 * );
 *
 * // => [{ 'x': 2 }]
