Types for geometry-local reference vectors.
These types represents points and displacement vectors in the reference frame defined in the auxiliary detector geometry box from the GDML geometry description. No alias is explicitly defined for the LArSoft global vector types, geo::Point_t and geo::Vector_t. Remember the LocalPoint_t and LocalVector_t vectors from different instances of geo::AuxDetGeo have the same type but are not compatible.
