function findWhere(collection, source) {
	      return find(collection, baseMatches(source));
	    }
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`.

@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'
