[nag] Changing Priority Structure

[Johannes Mock]

Hi

Is it possible to change the structure of the priority?
many task-systems work with simple priority-structure using only 3+1
levels (high, medium and low, and of course "unset priority") others
work with priority-structure using 10 levels (mostly with level 10 as
"unset priority").
Nag works with a 5 level priority-structure. Is there any possibility to
change this?
