Digitize the time ordered hits and write them to the digit format specific for the detector technology.

A new MuonSimHitContainer pointer is parsed to also create the MuonSDO. If a new SDO should be added to the container plese use the addSDO() method as defined below.

Reject hit within the dead time interval
