Started to port Jamroot etc. to be used also with CLANG80/LLVM as an alternative compiler. Also fixed some minor issues according to C++ standard conformity that G++ usually ignores (due to 'language extensions').

pretection against round-off errors of 4-vectors with masses around 0 (e.g. photons) in dyn functions

fixed d-functions for prod decays in e+e-; introduced background terms for P-vector; added particles in pdt-table

switched from   //  std::map<std::thread::id, std::map<std::string, complex<float> > > _cachedDynMap; to cachedAmpIdMap for performance improvement

removed last map with string keys in data structure; performance improvement, reduction of memeory for fits with radiative Psi decays in tensor formalism II
