#include <Chi2ChargeMeasurementEstimator.h>
A Chi2 Measurement Estimator, checking also the charge of the cluster. Computhes the Chi^2 of a TrajectoryState with a RecHit or a Plane. The TrajectoryState must have errors. If the cluster passes the chi2 cut, the charge is checked. This cut can be bypassed for high-pt cut. Works for any RecHit dimension.
