Holding structure for a number of track rendering parameters.

Calculates path taking into account the parameters.

NOTE: Magnetic field direction convention is inverted.

This is decoupled from TEveTrack/TEveTrackList to allow sharing of the Propagator among several instances. Back references are kept so the tracks can be recreated when the parameters change.

TEveTrackList has Get/Set methods for RnrStlye. TEveTrackEditor and TEveTrackListEditor provide editor access.

Enum EProjTrackBreaking_e and member fProjTrackBreaking specify whether 2D projected tracks get broken into several segments when the projected space consists of separate domains (like Rho-Z). The track-breaking is enabled by default.
