Detailed Description

BreakupProduct holds information about the fragments created by nuclear breakup in incoherent eA collisions. They essentially hold the results of Gemini++ the Monte Carlo used to describe the nuclear breakup. Each fragment from Gemini++ is stored as a BreakupProduct structure and kept in a vector that is later passed and stored in the event record if nuclear breakup is switched on (via runcard or programmatically). The emission time of the fragment is in units of 10^-21 seconds since the creation of the compound nucleus in the nucleus rest frame. This unit is common in NP and we left it as provided by Gemini. Note that the 4-momentum (p) is already boosted into the Sartre lab frame. 4-momenta are not expressed per nucleon here as it is done in the main event record.
