void DEventProcessor_track_hists::hit_info_t::FindLR	(	vector< const DMCTrackHit * > &	mctrackhits,
		const DLorentzDeflections *	lorentz_def = NULL
	)

Decided on whether or not the reference trajectory is on the correct side of the wire based on truth information.

Upon entry, the rt, wire, and rdrift members should be set. The remaining fields are filled in on return from this method.

Essentially, this will look through the DMCTrackHit objects via the DTrackHitSelectorTHROWN::GetMCTrackHit method to find the truth point corresponding to this hit (if any). It then compares the vector pointing from the point of closest approach on the wire to the DOCA point so a similar vector pointing from the same place on the wire to the truth point. If the 2 vectors are within +/- 90 degrees, then the trajectory is said to be on the correct side of the wire.
