If the 'MuonEntry'
TrackRecordCollection is not found, the
algorithm crashes; I don't think this is the desired result.
ATH_CHECK to retrieve the collection, the
StatusCode is checked but wasn't assigned for us in this call
This commit replaces the
ATH_CHECK in favor of an explicit check
of the return value of the
SG::retrieve(). Now, if the
TrackRecordCollection is not found, a warning is displayed and
the algorithm continues.
Also updated the copyright.
