Settings Library

Nice. Has even less lines of code than my settings-library

I just have two questions:
- Why do you do while($row = $query->fetch_assoc()) instead of foreach ( $query->result() as $row )? I'm always using the second way (with caching of course) so I'm just curious why you chose to use the first way.
- Does one really need the checks on if ( $this->ci === null ) and if ( $this->items === null ) One could simple run the get_instance() function in the constructor and the _refresh_items() method without the preceding check, can't we?

I even like the way you store the values for false, true, null and empty. I never really had thought of this one within my settings-library.

If you wanna have a look at an older and almost deprecated version, you can do so here.
