	/// \brief Definition of ReliabilityConfidenceCombinator functionality.
	///
	/// \note based on Maximilian Goetzinger (maxgot@utu.fi) code in
	/// CAM_Dirty_include SA-EWS2_Version... inside Agent.cpp
	///
	/// \note By defining and setting Reliability_trace_level it is possible to
	/// change the level to which it should be traced. \note All classes throw
	/// runtime errors if not all things are set
	///
	/// \note should the Reliability be capped?
