[Rivet] running all rivet analyses using small statistics in GENSER tests

[Dmitri Konstantinov]

Dear rivet experts,

In Genser I would like to implement quite simple test which runs all 
rivet analyses using arbitrary small hepmc file...
But it sees that is not that simple. Even with "--ignore-beams" several 
analyses throw assertions like:

       // Get an index for the beam energy
       isqrts = -1;
       if (fuzzyEquals(sqrtS(), 900*GeV)) isqrts = 0;
       else if (fuzzyEquals(sqrtS(), 7*TeV)) isqrts = 1;
       assert(isqrts >= 0);

python: ALICE_2012_I1181770.cc:24: virtual void 
Rivet::ALICE_2012_I1181770::init(): Assertion `isqrts > 0' failed.
python: ATLAS_2010_S8894728.cc:26: virtual void 
Rivet::ATLAS_2010_S8894728::init(): Assertion `isqrts >= 0' failed.
python: ATLAS_2011_S8994773.cc:26: virtual void 
Rivet::ATLAS_2011_S8994773::init(): Assertion `isqrts >= 0' failed.
python: ATLAS_2012_I1091481.cc:36: virtual void 
Rivet::ATLAS_2012_I1091481::init(): Assertion `isqrts >= 0' failed.
python: CDF_2012_NOTE10874.cc:28: virtual void 
Rivet::CDF_2012_NOTE10874::init(): Assertion `isqrts >= 0' failed.

And several fails with message like:

Rivet 2.1.2 running on machine lxplus0249.cern.ch (x86_64)

They are:
