Detailed Description

======= VXDGeometry ==========
Helper class for VXD geomtry transformations: from lab frame to ladder frame coordinates and inverse.

The ladder reference system has its origin at the middle of the sensitive box in x and y, where the x-coordinate runs along the thickness of the ladder and t he y coordinate runs along its width. The z coordinate is the same as in the lab frame.
