mcEventWeight branch never filled about factorytools

Probably because this is an int....

Will investigate when I get to CERN.

Setting this to a float doesn't work. Something deeper here. :(

This goes back to this problem where for some reason, when we try to get the eventInfo object from the store from the BasicEventSelection algorithm, it doesn't work. So in CalibrateST, we've re-grabbed the object from the Event and no longer has the object.

We could hack in the mceventweight into the region calculator, but honestly we should spend a little bit of time to try and understand why we can't access the XAH eventInfo from the store since this will come up several times from various weights that XAH stores in it.
