Discuss luminosity setup for weighted events

[Juergen Reuter]

Discuss this part of the WHIZARD code which I humbly changed for the sake of a smooth cross-over to 2.0.3:

       luminosity = var_list_get_rval (sim%var_list, var_str ("luminosity"))
       !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
       !!! To be discussed for 2.0.4
       !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
       !!! if (sim%spar%unweighted) then
       !!!    luminosity = var_list_get_rval (sim%var_list, var_str ("luminosity"))
       !!! else
       !!!    luminosity = 0
       !!! end if

I give it high priority because we should discuss this quite early. The examples depend on it.

[Juergen Reuter]

I already vote in favour of removing that restriction, it is nevertheless useful to give a luminosity even for weighted events.

[Juergen Reuter]

Ok, I let myself be overruled, if TO and WK vote for setting the luminosity to zero (but I would issue at least a warning, better an error!) I would change the example for the LEP Higgs search accordingly. But my intent is to resolve this quickly, at the latest at our meeting in Siegen.

[Juergen Reuter]

Forbid the lumi set-up, issue an error.
