/**
 * Performs a deep comparison between two values to determine if they are
 * equivalent to each other. If a callback is provided it will be executed
 * to compare values. If the callback returns `undefined` comparisons will
 * be handled by the method instead. The callback is bound to `thisArg` and
 * invoked with two arguments; (a, b).
 *
 * @static
 * @memberOf _
 * @category Objects
 * @param {*} a The value to compare.
 * @param {*} b The other value to compare.
 * @param {Function} [callback] The function to customize comparing values.
 * @param {*} [thisArg] The `this` binding of `callback`.
 * @returns {boolean} Returns `true` if the values are equivalent, else `false`.
 * @example
 *
 * var object = { 'name': 'fred' };
 * var copy = { 'name': 'fred' };
 *
 * object == copy;
 * // => false
 *
 * _.isEqual(object, copy);
 * // => true
 *
 * var words = ['hello', 'goodbye'];
 * var otherWords = ['hi', 'goodbye'];
 *
 * _.isEqual(words, otherWords, function(a, b) {
 *   var reGreet = /^(?:hello|hi)$/i,
 *       aGreet = _.isString(a) && reGreet.test(a),
 *       bGreet = _.isString(b) && reGreet.test(b);

 *   return (aGreet || bGreet) ? (aGreet == bGreet) : undefined;
