	/**
	* The opposite of `mapValue` 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).
	*
	* @since 3.8.0
	* @category Object
	* @param {Object} object The object to iterate over.
	* @param {Function} iteratee The function invoked per iteration.
	* @returns {Object} Returns the new mapped object.
	* @see mapValue
	* @example
	*
	* mapKey({ 'a': 1, 'b': 2 }, function(value, key) {
	* return key + value
	* })
	* // => { 'a1': 1, 'b2': 2 }
