The station geo helpers provide for each muon chamber a reference coordinate system which is the baseline for the hough seeding and segment finding in the run 4 muon reconstruction. The position of the system is the the plane that's on the bisect between the first tube layer in the lower multilayer and the last tube layer in the upper multilayer of each Mdt chamber.
MuonTransformCache*: Add documentation and an additional getter function
MdtReadoutElement*: The transformation to the layer center points now to the exact center of the layer. Orientation still not changed w.r.t. the tube coordinate system (I.e. z-axis along the wire, x-axis pointing to the next layer, and y-axis going along the tube number)
