Detailed Description

Container of a single alignment point and methods to fill it.

An alignment point is defined by the track crossing point coordinates at the z of this plane, the cluster coordinates, the value of the local derivarives and the global derivatives at that point, the sensor id of this cluster. This class also offers to compute the track-cluster residual at this point.
