Callback routines for system transitions
These routines are called whenever a system transition like start/
stop of a run occurs. The routines are called on the following
occations:
frontend_init: When the frontend program is started. This routine
should initialize the hardware.
frontend_exit: When the frontend program is shut down. Can be used
to releas any locked resources like memory, commu-
nications ports etc.
begin_of_run: When a new run is started. Clear scalers, open
rungates, etc.
end_of_run: Called on a request to stop a run. Can send
end-of-run event and close run gates.
pause_run: When a run is paused. Should disable trigger events.
resume_run: When a run is resumed. Should enable trigger events.
