1. if a performed event is part of a set then mark the set complete when all events in it have been performed.
2. when a set is marked as complete it should be evaluated immediately.
3. once a complete set is evaluated it is never evaluated again (although incomplete sets may be evaluated again)
4. if a performed location is marked as a 'calc' location and all sets have been evaluated then the calc. is executed.
5. if a performed location is past the next-calc-loc then the calc is executed.
6. if a calc has already been executed and an event that is part of the calc is recieved then the
associated set is updated and the calc is executed again.
7. if a performed event occurs on a trigger location then the section update is executed.
8. if a performed event occurs on a trigger location that has already been executed then the section update is NOT
performed again.
