/**
 * Performs a partial deep comparison between `object` and `source` to
 * determine if `object` contains equivalent property values.
 *
 * **Note:** This method is equivalent to `_.matches` when `source` is
 * 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.

 * @example
 *
 * var object = { 'a': 1, 'b': 2 };
 *
 * _.isMatch(object, { 'b': 2 });
 * // => true

 * _.isMatch(object, { 'b': 1 });
