• Analysis/GraphvizPlot.cc (dofinish): Made the message sent to

cout optional.

• lib/inputerror.pm (inputerror): Added small PERL module for

reading numbers with errors as written out bu ThePEG.

• Vectors/HepMCTraits.h, Vectors/HepMCConverter.tcc,

Vectors/HepMCConverter.h: Included support for cross sectio
information and made the traits class implement cross sections,
pdf's and units depending on what is set in HepMCDefs.h.

Also reordered the particles according to their numbering as an
alternative to CMS's suggested "topological" sorting.

This will hopefully fix herwig:ticket:153

• include/Makefile.am (CONFIGHEADERS): Make sure

Config/HepMCHelper is properly symlinked.

• Analysis/GraphvizPlot.cc (particleName): Added helper function

for getting the name of a particle to be able to handle remnant
particles (which have code 82).
