//
//  SiPixelTemplate2D.h (v1.03)
//
//  Full 2-D templates for cluster splitting, simulated cluster reweighting, and improved cluster probability
//
// Created by Morris Swartz on 12/01/09.
// Copyright 2009 __TheJohnsHopkinsUniversity__. All rights reserved.
// 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
//
//
 
// Build the template storage structure from several pieces
