Revert to a previous setup of VertexFit except for some bug fix
Changed the convergence criteria of VertexFit
Added dump face position to SRecTrack so that it could be used for dump cut
First try of mimicing what GMC does to calculate wire position
Changed to coordinate calculation used in GMC
Bug fix in matrix-vector multiply
Final version of GeomSvc which uses exactly the same way of calculating line-plane interception
Minor change in GeomSvc
Re-arranged the code: 1. use new coordinate calculation according to GMC; 2. move the simple swimming method from FastTracklet to SRecTrack
