Add a separate MaterialSource flag for ACTS tracking geometry
Previously, the ACTS tracking geometry was using TrackingGeometry.MaterialSource
, and was explicitly checking the content to not break with the default value of COOL
.
This MR introduces a new flag Acts.TrackingGeometry.MaterialSource
. I'm adding Acts
at the beginning here, because I was thinking that we might want to introduce other flags scoped under ACTS down the road.
