Creates an object with the same keys as `object` and values generated by
running each own enumerable property of `object` through `iteratee`. The
iteratee function is bound to `thisArg` and invoked with three arguments;
(value, key, object).

If a property name is provided for `iteratee` the created "_.property"
style callback returns the property value of the given element.

If an object is provided for `iteratee` the created "_.matches" style
callback returns `true` for elements that have the properties of the given
object, else `false`.

@category Object
@param {Object} object The object to iterate over.
@param {Function|Object|string} [iteratee=_.identity] The function invoked
 per iteration. If a property name or object is provided it is used to
 create a "_.property" or "_.matches" style callback respectively.
@param {*} [thisArg] The `this` binding of `iteratee`.
@returns {Object} Returns the new mapped object.
@example

_.mapValues({ 'a': 1, 'b': 2, 'c': 3} , function(n) { return n * 3; });
// => { 'a': 3, 'b': 6, 'c': 9 }

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

// using the "_.property" callback shorthand
_.mapValues(users, 'age');
// => { 'fred': 40, 'pebbles': 1 } (iteration order is not guaranteed)
