 * This method is like `_.get` except that if the resolved value is a function

 * @category Object
 * @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) } }] };
