Detailed Description

One-dimensional (u, v, or x) track stubs and associated hits.

The QwTreeLine has a pointer to a set of hits. It is passed to various track fitting procedures and carries around the fit results.

Todo:: This class needs a non-trivial copy constructor which ensures that the hits are copied correctly.
