> The functionality should not be affected. Instead of passing 2 numbers (1 for
> # of preceding rows and 1 for # of following rows), we will pass
> WindowFrameDef object around. In the following subtasks, it will be used to
> support additional window like {{rows between x preceding and y preceding}}
> and {{rows between x following and y following}}.
