* Resolves the value of property `key` on `object`. If the value of `key` is
* a function it is invoked with the `this` binding of `object` and its result
* is returned, else the property value is returned. If the property value is
* `undefined` the `defaultValue` is used in its place.
* This method is like `_.get` except that if the resolved value is a function
* it is invoked with the `this` binding of its parent object and its result
* is returned.

* @memberOf _
* @category Object
* @param {Object} object The object to query.
* @param {string} key The key of the property to resolve.
* @param {*} [defaultValue] The value returned if the property value
* resolves to `undefined`.
* @param {Array|string} path The path of the property to resolve.
* @param {*} [defaultValue] The value returned if the resolved value is `undefined`.
* @returns {*} Returns the resolved value.
* @example
*
* var object = { 'user': 'fred', 'age': _.constant(40) };
* var object = { 'a': [{ 'b': { 'c1': 3, 'c2': _.constant(4) } }] };
*
* _.result(object, 'user');

* _.result(object, 'age');
