//  SiPixelTemplateSplit.cc (Version 2.30)
//
//  Procedure to fit two templates (same angle hypotheses) to a single cluster
//  Return two x- and two y-coordinates for the cluster
//
//  Created by Morris Swartz on 04/10/08.
//
//  Incorporate "cluster repair" to handle dead pixels
//  Take truncation size from new pixmax information
//  Change to allow template sizes to be changed at compile time
//  Move interpolation range error to LogDebug
//  Add q2bin = 5 and change 1-pixel probability to use new template info
//  Add floor for probabilities (no exact zeros)
//  Add ambiguity resolution with crude 2-D templates (v2.00)
//  Pass all containers by alias to prevent excessive cpu-usage (v2.01)
//  Add ambiguity resolution with fancy 2-D templates (v2.10)
//  Make small change to indices for ambiguity resolution (v2.11)
//  Tune x and y errors separately (v2.12)
//  Use template cytemp/cxtemp methods to center the data cluster in the right place when the templates become asymmetric after irradiation (v2.20)
//  Add charge probability to the splitter [tests consistency with a two-hit merged cluster hypothesis]  (v2.20)
//  Improve likelihood normalization slightly (v2.21)
//  Replace hardwired pixel size derived errors with ones from templated pixel sizes (v2.22)
//  Add shape and charge probabilities for the merged cluster hypothesis (v2.23)
//  Incorporate VI-like speed improvements (v2.25)
//  Improve speed by eliminating the triple index boost::multiarray objects and add speed switch to optimize the algorithm (v2.30)
