Actually I spent some time looking at the implmentation of this and 
there doesn't seem to be a sensible way to implement this. I think what 
I really want is some sort of 'id' based file rotation. In that light I 
suppose I could use the time_based_rotation and supply my own function 
that rotates based on a changing 'id'. Perhaps this could be generalised 
in the library to be a 'triggered_rotation' where some of the current 
implementations happen to be time based?
