  // NOTES: 
  // 1. StEEmcDbMaker has some limitations so beware of the following
  // ( complaints to appropriate autors) 
  // * StEEmcDbMaker works _only_ for single run , so make sure that
  //   your *.lis containf files for one run only, otherwise it will crash 
  //   like Windoza
// not true anymore - OG
  // 2. EEmcTTMMaker main "product" is a list of EEmcTTMatch'es which in turn 
  //   are EEmcTower plus a list of StMuTrack's that fullfill certain criteria.
