An upgraded issue of the parton and hadron cascade model, PACIAE 2.2

Running time: PACIAE 2.2 has three versions of PACIAE 2.2a, 2.2b, and 2.2c. PACIAE 2.2a is for the elementary collision, such as pp, pp, and e+e− collisions, as well as the lepton-nucleon DIS, with input file of usux.dat. PACIAE 2.2b and PACIAE 2.2c are for the nuclear-nucleus collision of p+A and A+B as well as the lepton-nucleus DIS with input file of usu.dat. PACIAE 2.2b and 2.2c are similar in the physical contents but are different in the topological structure (see text for the details).
