0027
0028     This class is used as a kind of "dummy" wrapper for particles experiencing no
0029     initial state radiation. Therefore the internal structure is pretty simple,
0030     and there is no PDF_Base related to it, quite in contrast to the Structure_Function.
0031
0032     Its type is "(None)".
