const ref to EventContext when using Gaudi::Hive::currentContext(), and replace vector size()==0 with empty()
Hello,
When retrieving the event context via Gaudi::Hive::currentContext(), it is probably more efficient to use a const ref. Not the primary goal of this MR, but when vector size() was used to check for empty vectors, empty() is now used.
Cheers, Bertrand
