Switched to the new version of GeoModel
The new version of GeoModel
contains fixes to cppcheck warnings originally
implemented by Scott in !47594 (merged).
Athena clients have been adapted to these changes.
Several build_externals.sh
scripts updated with the new version of GeoModel
master.
FYI @nstyles , I've tested my changes by using Run 4 simulation ART tests
