RT::Action::EscalatePriority

=head1 DESCRIPTION

EscalatePriority is a ScripAction which is NOT intended to be called per
transaction. It's intended to be called by an RT escalation daemon.
(The daemon is called escalator).

EsclatePriority uses the following formula to change a ticket's priority:

Priority = Priority + (( FinalPriority - Priority ) / ( DueDate-Today))

Unless the duedate is past, in which case priority gets bumped straight
to final priority.

In this way, priority is either increased or decreased toward the final priority
as the ticket heads toward its due date.
