enforce a more local combination
few steps for checking
saving the itype in meson and baryon list,
not using it yet
exclude last element, as API remains unchanged
give full information to creation mechanism.
Filter photons with correct position of mass!
changing to a more complex production of particles
ready for testing new formula for different partons
make sure order of returned parton masses does not
introduce a bias on antiparticle production
testing create_duplets
transition for baryon case
no need to recalculate
local changes in order to fragment hadrons
