 8   * Creates a function that performs a partial deep comparison between the
 9   * value at `path` of a given object to `srcValue`, returning `true` if the
10   * object value is equivalent, else `false`.
11   *
12   * **Note:** Partial comparisons will match empty array and empty object
13   * `srcValue` values against any array or object value, respectively. See
14   * `_.isEqual` for a list of supported value comparisons.
15   *
16   * **Note:** Multiple values can be checked by combining several matchers
17   * using `_.overSome`
