sPHENIX EMCal discussion

["Huang, Jin" <jhuang AT bnl.gov>]

Hi, John and Martin

Thanks for the information. As you may see in the GitHub email list, both 
features are put into a new code base for 2017 production. It will be 
available in the next nightly build. It was not yet tested with the coming 
2017 data, as it probably requires a few iterations with real data to get 
things stringed out properly. Nevertheless, it runs find with old 2016 data.

Cheers,

Jin
