Remove daqstart daqstop from pg_single. This now relies on daq_enable
being called before.
Implementd daq_enable daq_disable functions
Sorry - necessary change to hrmap.py due to different working
scheme of the pattern generator via API. This is a bit cleaner I
guess since we can just put the signals as strings in.
Implement pg_loop and pg_stop functions - just mapping to
daqTriggerLoop() and daqTriggerLoopHalt().
Furthermore adding some dead ("pass") functions which are not needed
when using the API. We could probably also remove them from the tests.
Impelement get_data() function needed by the HR tests. This works as
far as I could tests, but the raw vectors are not returned (just empty
lists) because they are not used anywhere. Could be implemented but
will not do unless really needed...
