* Performs a deep comparison between each element in `collection` and the
* source object, returning the first element that has equivalent property
* values.
*
* **Note:** This method supports comparing arrays, booleans, `Date` objects,
* numbers, `Object` objects, regexes, and strings. Objects are compared by
* their own, not inherited, enumerable properties. For comparing a single
* own or inherited property value see `_.matchesProperty`.
*

* @memberOf _
* @category Collection
* @param {Array|Object|string} collection The collection to search.
* @param {Object} source The object of property values to match.
* @returns {*} Returns the matched element, else `undefined`.
* @example
*
* var users = [
* { 'user': 'barney', 'age': 36, 'active': true },
* { 'user': 'fred', 'age': 40, 'active': false }
* ];
*
* _.result(_.findWhere(users, { 'age': 36, 'active': true }), 'user');
* // => 'barney'
*
* _.result(_.findWhere(users, { 'age': 40, 'active': false }), 'user');
* // => 'fred'
