Creates an object with the same keys as `object` and values generated
by running each own enumerable string keyed property of `object` thru
`iteratee`. The iteratee is invoked with three arguments:
(value, key, object).

@param {Object} object The object to iterate over.
@param {Array|Function|Object|string} [iteratee=_.identity]
 The function invoked per iteration.
@returns {Object} Returns the new mapped object.

@example

var users = {
  'fred':    { 'user': 'fred',    'age': 40 },
  'pebbles': { 'user': 'pebbles', 'age': 1 }
};

_.mapValues(users, function(o) { return o.age; });
// => { 'fred': 40, 'pebbles': 1 } (iteration order is not guaranteed)

// The `_.property` iteratee shorthand.
_.mapValues(users, 'age');
// => { 'fred': 40, 'pebbles': 1 } (iteration order is not guaranteed)
