> Almost all methods in FilterList do work on behalf of the passed list of 
> filters, which - you guessed it - is always an ArrayList and we always 
> iterate over those with an iterator. Multiple of these methods are called for 
> each row leading to creating about 10 Itrs for every single row touched 
> (whether filtered or not)
