| * The opposite of `_.mapValues`; this method creates an object with the |

| * string keyed property of `object` thru `iteratee`. The iteratee is invoked |
| * with three arguments: (value, key, object). |

| * @category Object |
| * @param {Object} object The object to iterate over. |
| * @param {Function} [iteratee=_.identity] The function invoked per iteration. |
| * @returns {Object} Returns the new mapped object. |
| * @see _.mapValues |
| * @example |
| * |
| * _.mapKeys({ 'a': 1, 'b': 2 }, function(value, key) { |
