Error if no event passed.

Event number counter.

Set units to be GeV and mm, to agree with Pythia ones.

1a. If there is a HIInfo object fill info from that.

Fill particle information.
Fill vertex information.

Update vertex position if necessary.

Reserve memory for the event.

Here we assume that the first two particles are the beam particles.

Add particles and vertices in topological order.

Attributes should be set after adding the particles to event.

Colour flow uses index 1 and 2.

If hadronization switched on then no final coloured particles.

Check for particles which come from nowhere, i.e. are without mothers or daughters. These need to be attached to a vertex, or else they will never become part of the event.

Check for particles not added to the event. NOTE: We have to check if this step makes any sense in the HepMC event standard.

Also check for free partons (= gluons and quarks; not diquarks?).

Store PDF, weight, cross section and other event information. Flavours of incoming partons.

Store PDF information.

Store process code, scale, alpha_em, alpha_s.

Store event weights.

Store cross-section information in pb.

First set atribute to event, such that GenCrossSection::set_cross_section knows how many weights the event has and sets the number of cross sections accordingly.

If multiweights with possibly different xsec, overwrite central value

Done.
