/*
10
Given a track, evaluates the status of the track finding in the XY plane
11
the point of tangent of the circle to the reference point(in general the PrimaryVertex or the BeamSpot)
12
13
The approach is the following.
14
Given a track,
15
-extract the innermomentum at the innerpoint
16
-evalaute the radius of curvature and the center of the circle
17
-solving geometrical equation, evaluate the point of tangence to the circle, starting from the PV
18
-evaluate the status at this point of tangence T
