Detailed Description

Contains two TauolaParticle that are related by the same mother. Spin correlations are handled here.

An object of TauolaParticlePair contains two TauolaParticle that are related by the same mother. Generally this will be a tau+ and tau- or a tau and tau neutrino. For the case of event records that contain multiple instances of the same particle. eg. tau -> gamma tau or simply tau -> tau. Both the tau from the production vertex, and the final tau before the decay vertex are stored. This allows better handling of spin correlations. The decay is done in the rest frame of the final tau, where as the spin weight is calculated in the rest frame of the production tau. All spin weights are done in this class. Please refer to the decayTauPairs() method.
