This method is like `_.get` except that if the resolved value is a function
it's invoked with the `this` binding of its parent object and its result
is returned.

@param {Object} object The object to query.
@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 = { 'a': [{ 'b': { 'c1': 3, 'c2': _.constant(4) } }] };

_.result(object, 'a[0].b.c1');
// => 3

_.result(object, 'a[0].b.c2');
// => 4

_.result(object, 'a.b.c', 'default');
// => 'default'

_.result(object, 'a.b.c', _.constant('default'));
// => 'default'
