1. Maybe it is a good idea to make ScanPlan belongs to Beamtme like what we have for current xpdAcq There are two advantages to this approach:

   • we don't have to keep updating registered plan, we can simply maintain ct, Tramp and tseries

   • Unify plan input to RE and still make bluesky plan possible

     class Customized_RE(RunEngine)
     ....
     if isinstance(plan, ScanPlan):
     

plan.factory

code itself, basically a copy of Dan's subtracted tiff exporter:

class SubtractedTiffExporter(LiveTiffExporter):
   "Intercept images before saving and subtract dark image"

   def start(self, doc):
       # The metadata refers to the scan uid of the dark scan.
       #if 'dark_frame' not in doc:
 dark_sub = True

## customized count
def delayed_count(detectors, shutter_config, interval=None, num=1, *, md=None):
    """
    Take one or more readings from detectors.
    Parameters
    ----------
    detectors : list
        list of 'readable' objects
    gasses : list of string
        name of gasses want to alterna
