Handler class for downscale factors read from the OCDB. The class is used as singleton class shared among several wagons. In order to access the cdb connect handler the Instance function is used

AliEmcalDownscaleFactorsOCDB *downscalehandler = AliEmcalDownscaleFactorsOCDB::Instance();
downscalehandler->SetRunNumber(196310);

Accessing the downscale factor requires a full name of the trigger class, including trigger cluster:

double ds = downscalehandler->GetDownscaleFactorForTriggerClass("CINT7-B-NOPF-ALLNOTRD");

Attention: The class does not manage OCDB access. When used in analysis, the CDB connect wagon is expected to run before.
