/// ProxyStripTopology
///
/// Class derived from StripTopology that serves as a proxy to the
/// actual topology for a given StripGeomDetType. In addition, the
/// class holds a pointer to the surface deformation parameters.
/// ProxyStripTopology takes over ownership of the surface
/// deformation parameters.
///
/// All inherited virtual methods that take the
/// predicted track state as a parameter are reimplemented in order
/// to apply corrections due to the surface deformations.
//
/// The 'old' methods without the track predictions simply call
/// the method of the actual StripTopology.
/// While one could easily deduce corrections from the given
/// LocalPosition (and track angles 0) when converting from local frame
/// to measurement frame, this is not done to be consistent with the
/// methods converting the other way round where the essential y-coordinate
/// is basically missing (it is a 1D strip detector...)
