Improve error messages

[kilian]

This ticket is for reporting incomprehensible or ambiguous error messages.

OK, I'll start with Ticket #188.1, an error message I don't understand: The input file is

process hh = e1, E1 -> H, H

compile

sqrts = 500 GeV
beams = e1, E1

integrate (hh) { iterations = 3:5000, 2:5000 }

and W2 gives the error message

| Integrating process 'hh'
*** Fatal error: Process 'hh': beam/process mismatch (collision/decay)

I think it's trying to tell me that there is no process e+e- -> HH for Whizard/Omega?...

Forgot to mention: Probably related to #159 as the error message also appears for the input file I gave there (bug8.sin)

This issue has been addressed with the extended multi-line messages in r1750/51. From now on that topic allows to include longer error messages, that give the user plenty of information. I would move the rest of the fest of the error message to the general validation ticket. Closing this one.
