Using AliRoot utilities?

[ginnocen]

@preghenella. In the O2 converter for Run3 we are currently using some utilities from AliRoot for performing some truncation (AliMathBase::TruncateFloatFraction). I didn't use them for the moment cause I was not sure we wanted to go in that direction. I temporary removed the truncation. I wanted to know what you think about it.
I still have to check that the absence of truncation has the only effect of making the dataset bigger as I expect.

As discussed with Peter, we will copy the piece of code from Aliroot for the truncation.

I would possibly avoid to link this package to Aliroot because it would need Aliroot built with o2 defaults and available on Grid

The truncation code can be put in the converter.h

OK I can take care of it today.
