PanTauAlgs: enable thread-checker and fix warnings
PanTauAlgs modifies (the mass of) the TauJet
constituents when building the PFO. To avoid const_cast
add a non-const accessor in TauJet_v3
. Since ElementLink
does not provide non-const access to the pointed to object, take the detour via the container itself.
Note, this is not an EDM change. Just an addition to the interface.
