//
//  SiPixelTemplateReco2D.cc (Version 2.90)
//  Updated to work with the 2D template generation code
//  Include all bells and whistles for edge clusters
//  2.10 - Add y-lorentz drift to estimate starting point [for FPix]
//  2.10 - Remove >1 pixel requirement
//  2.20 - Fix major bug, change chi2 scan to 9x5 [YxX]
//  2.30 - Allow one pixel clusters, improve cosmetics for increased style points from judges
//  2.50 - Add variable cluster shifting to make the position parameter space more symmetric,
//         also fix potential problems with variable size input clusters and double pixel flags
//  2.55 - Fix another double pixel flag problem and a small pseudopixel problem in the edgegflagy = 3 case.
//  2.60 - Modify the algorithm to return the point with the best chi2 from the starting point scan when
//         the iterative procedure does not converge [eg 1 pixel clusters]
//  2.70 - Change convergence criterion to require it in both planes [it was either]
//  2.80 - Change 3D to 2D
//  2.90 - Fix divide by zero for separate 1D convergence branch
//
