separate model for nuclear remnants and fragmentation
Follow-up to a comment by K. Bernlöhr at the c8 workshop.
The HE models Sibyll, QGSjet and Epos all treat the fragmentation of nuclei differently (also depending whether the nucleus is projectile or target). Similar to #65 (closed) !430 (merged) it may be possible to separate the treatment of nuclear remnants from the hadronic interaction in a separate process.
