Short summary for Jan 19,2017
=======================
Different new variants were tested.

1. Accounting known vertex in seed finder;(+)
2. Finding of the seeds from In to Out, due to first 6 dislks give better hits ;(-)
3. Find seeds only on the base of first 6 disks; (-)
4. Varying of tolerance  constant(+)

In result again winner KNN=0,Reuse=1 Eff=87>86  IdT=75>70, Better than before.
======================================================


Non Uniform mag field
=================
What should be done:

1. THelixTrack with mag field NOT along Z. ( Not a big problem)
2. Track following by Runge-Cutta . (Done)
3. Derivatives/errors for Runge-Cutta. (Not easy, but first try to use derivatives from ThelixTrack)

Table of Quality & effoiciency

KNN	ReUse	Eff GlobGood	Eff Prim	IdTruth Glob
0	0	112%	62%	58%
1	0	108%	74%	57%
0	1	91%	86%	70%
1	1	84%	80%	70%

  So the winner is KNN=0 Reuse=1 GlobEff = 91%  PrimEff = 86% IdTruth = 70%
