| * The opposite of `_.mapValues`; this method creates an object with the | |
| * same values as `object` and keys 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 {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) { | |
