Detailed Description

Description: High level class for reconstructed decay candidates:

• only constructor interfaces are defined in this class
• functions returning results are defined in base classes: BPHDecayMomentum : decay products simple momentum sum BPHDecayVertex : vertex reconstruction BPHKinematicFit : kinematic fit and fitted momentum sum
