Detailed Description

: Helper class to connect the aligned transformations of each active sensor(layer) with the Acts::Surfaces.

It's actively used in the surface factories of the MuonReadoutElement. The SurfaceCache takes a pointer to the TransformCache managing the local to global transformation of the corresponding layer and the DetectorType. The latter is needed to pass the proper AlignmentStore from the Geometry context to the transform cache. Once constructed, the TransformCache is parsed to the surface construction mechanism of the Acts::Surface. The resulting shared_ptr is then parsed to the SurfaceCache.
