//
//  SiPixelTemplate2D.h (v2.65)
//
//  Full 2-D templates for cluster splitting, simulated cluster reweighting, and improved cluster probability
//
// Created by Morris Swartz on 12/01/09.
// V1.01 - fix qavg_ filling
// V1.02 - Add locBz to test if FPix use is out of range
// V1.03 - Fix edge checking on final template to increase template size and to properly truncate cluster
// v2.00 - Major changes to accommodate 2D reconstruction
// v2.10 - Change chi2 and error scaling information to work with partially reconstructed clusters
// v2.20 - Add cluster charge probability information, side loading for template generation
// v2.21 - Double derivative interval [improves fit convergence]
// v2.25 - Resize template store to accommodate FPix Templates
// v2.30 - Fix bug found by P. Shuetze that compromises sqlite file loading
// v2.35 - Add directory path selection to the ascii pushfile method
// v2.50 - Change template storage to dynamically allocated 2D arrays of SiPixelTemplateEntry2D structs
// v2.51 - Ensure that the derivative arrays are correctly zeroed between calls
// v2.52 - Improve cosmetics for increased style points from judges
// v2.60 - Fix FPix multiframe lookup problem [takes +-cotalpha and +-cotbeta]
// v2.61a - Code 2.60 fix correctly
// v2.65 - change double pixel flags to work with new shifted reco code definition
//

// Build the template storage structure from several pieces
