/**

 * Creates a function that performs a partial deep comparison between a given

 * object and `source`, returning `true` if the given object has equivalent

 * property values, else `false`.

 *

 * **Note:** The created function is equivalent to `_.isMatch` with `source`

 * partially applied.

 *

 * Partial comparisons will match empty array and empty object `source`

 * values against any array or object value, respectively. See `_.isEqual`

 * for a list of supported value comparisons.

 * @param {Object} source The object of property values to match.

 * @returns {Function} Returns the new spec function.

 * @example

 *

 * var objects = [

 *   { 'a': 1, 'b': 2, 'c': 3 },

 *   { 'a': 4, 'b': 5, 'c': 6 }

 * ];

 *

 * _.filter(objects, _.matches({ 'a': 4, 'c': 6 }));
