Detailed Description

Simplified relation creator only creating relations between states of CDC Reco Track seeds and states with SpacePoints, that: (a) for the seed states: connect every seed with every lst hit of the SVD Reco Tracks (b) for the hit states: are in the same SVD Reco Track and follow each other directly.

So if one travels the path of the relations, one would perfectly travel the path of one SVD track.
