Add forward compatibility functions for Track V1
Provide freestanding functions for LHCb::Event::v1::Track
which can be found by ADL,
and provide forward compatible ways of eg. getting Measurements
, and which provide
backwards compatible closestState
functionality.
Use the above closestState
in VeloExpectation, MuonTrackAlignMonitor, and TrackCaloMatchMonitor,
which should make them insensitive to LHCb!1696 (merged).
