[Rivet] AGILe 1.3.0 alpha0 for testing, and Genser HERWIG LHEF reading

[Andy Buckley]

Hi Gensers and Riveteers,

I've just uploaded an alpha0 tarball of the next AGILe release, 1.3.0, 
to the usual place on the HepForge website:
http://www.hepforge.org/downloads/agile
Can you please test this (with the mcplots dev server if possible?) and 
let me know of any issues? Thanks :)

There are several nice features in this release-to-be, including fixes 
in the HERWIG+AlpGen interface, making the HERWIG status codes behave 
like the HepMC standard for better interaction with Rivet studies of 
unstable hadrons, making it possible to read in POWHEG and other events 
in LHEF format with PYTHIA and HERWIG, and a built-in way to apply 
arbitrary parameter transformations. Hence the proper version number change.

I have been told by Simone Alioli, who provided the HERWIG LHEF reading 
code, that the version of HERWIG installed in the Genser repository has 
had the necessary user functions replaced by do-nothing dummies, so it 
needs to be hacked to work with this new AGILe functionality. Is there 
any possibility that the LHEF functions could be added (I have examples) 
as standard, or another way provided to allow this to work "out of the box"?

Daniel W, I hope that we will have the AGILe 1.3.0 release quite soon, 
and maybe we'll also want to modify the bundled HERWIG for LHEF reading, 
so best to hold back a *little* on a new release of the VM to avoid 
duplicating too much work!

Thanks again, everyone!

Andy
