Ceres is not able to read non compact Eventio

[dbaack]

When ceres is executet on non compact EventIO data non event is processed through ceres. I tested it by using the same simulation with compact and non comapct data. In case of compact multiple events get processed through the simulation chain.

I think the most possible reason for this error is the return value of

Int_t MPhotonData::FillEventIO(Float_t f[8]){
...
return n-1;
}

in

https://trac.fact-project.org/browser/trunk/Mars/msim/MPhotonData.cc

The function used for the compact format uses a "return 1;"
