Detailed Description

Class to handle pseudo-measurements in fitters and on track objects.

Such virtual measurements are typically used to feed crude values into track fitters for otherwise unconstraint fit parameters. Inherits from the common Trk::MeasurementBase but NOT from Trk::RIO_OnTrack since it is not necessarily connected to a "real" identifier, PRD or detectorElement. Through the Trk::MeasurementBase inheritance this class can be stored and persistified.
