/// @brief  Implementation of the AliHLTReadoutList class.
///
/// The AliHLTReadoutList class is used as an interface to the AliHLTEventDDL
/// structure. It makes it easy to manipulate the bits in this structure, which
/// define what DDLs should be readout by DAQ.
/// Several operators are also overloaded which are meant to be used in the trigger
/// menu specification for the AliHLTGlobalTrigger. It allows one to construct
/// expressions for the readout lists, which is necessary to be able to evaluate
/// or compose the final readout list, given multiple input readout lists received
/// from individual components that derive from AliHLTTrigger.
