Detailed Description

Class for a generic track segment that holdes polymorphic Trk::MeasurementBase objects, it extends the Trk::Segment base class.

Trk::MeasurementBase objects of different type can be used to describe this track segment. The fitted Trk::LocalParameters such as the associated ErrorMatrix are directly forwarded to be stored in the Trk::MeasurementBase base class.

A Surface has to be provided to give the reference frame the \ Trk::TrackSegment is expressed to.
