TauolaParticlePair::TauolaParticlePair

(

std::vector< TauolaParticle * > &

particle_list

)

This constructor takes the TauolaParticle and traverse the event structure to find the mother, partner tau or tau neutrino and assosiated final and production versions. Once a TauolaParticlePair object has been created in this way it is ready to be decayed via decayTauPairs().
