Detailed Description

Generates monopole-like axial tracks from hit using special leaf postprocessing.

Implements Legendre transformation of the drift time circles. This is a module, performing tracking in the CDC. It is based on the paper "Implementation of the Legendre Transform for track segment reconstruction in drift tube chambers" by T. Alexopoulus, et al. NIM A592 456-462 (2008).

NOTE currently performs legendre search for tracks of low curvature, with no postprocessing TODO:

• search for strictly straight tracks (q=0.00) without quadtree
• axial track postprocessing
