As some information in a Les Houches Event File init block is only known
at the end of generation, some programs choose to output this as a
separate file. If <code>Beams:LHEFheader</code> is given, information up
till the end of the init block is read from this file, with
the events themselves read as usual from the file given in
<code>Beams:LHEF</code>.
