General hook for setting detector attributes (Pilatus, Lambda)

An example hook on how to set detector attributes can be found here 13.2.1.

A more general example for adding any arbitrary number of detectors in the MG is':

class gh_pre_scan(Macro):
	param_def = [
	        ]
	def run(self):

		mg_name = self.getEnv( 'ActiveMntGrp')
		self.mg = PyTango.DeviceProxy( mg_name)
		self.mglist = self.mg.ElementList
                self.detector_list = []
		for elm in self.mglist:
			if elm.find('p100') != -1 or elm.find('p300') != -1 or elm == 'eiger' != -1 or elm == 'lmbd' != -1:
                            self.detector_list.append(elm)
		try:
		        detectorName = self.getEnv('2Ddetector')
                        if detectorName not in self.detector_list and detectorName in self.mglist:
                            self.detector_list.append(detectorName)
                except:
                        pass
                pilatusRoot = "/gpfs/current/raw"
                for dect in self.detector_list:
                    try:
                        HasyUtils.prepareDetectorAttrs( self, name = dect, rootDir = pilatusRoot)
                    except:
                        self.output( "gh_pre_scan: prepareDetectors return error for detector" % dect)

                return True
