/**
* 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.
*
* **Note:** Multiple values can be checked by combining several matchers
* using `_.overSome`

* @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 }));
* // => [{ 'a': 4, 'b': 5, 'c': 6 }]
*
* // Checking for several possible values
* _.filter(objects, _.overSome([_.matches({ 'a': 1 }), _.matches({ 'a': 4 })]));
* // => [{ 'a': 1, 'b': 2, 'c': 3 }, { 'a': 4, 'b': 5, 'c': 6 }]
