* Converts each object key to lowercase.
*
* ## Notes
*
* - The function only transforms own properties. Hence, the function does not transform inherited properties.
* - The function shallow copies key values.
*
* @param obj - source object
* @returns new object
*
* @example
* var obj1 = {
* 'A': 1,
* 'B': 2
* };
*
* var obj2 = lowercaseKeys( obj1 );
* // returns { 'a': 1, 'b': 2 }
