//
//  SiStripTemplate.h (v2.10)  [v1.0 based on SiPixelTemplate v8.20]
//
//  V1.05 - add VI optimizations from pixel template object
//  V1.06 - increase angular acceptance (and structure size)
//  V2.00 - add barycenter interpolation and getters, fix calculation for charge deposition to accommodate cota-offsets in the central cotb entries.
//  V2.01 - fix problem with number of spare entries
//  V2.10 - modify methods for cluster splitting to improve speed
//
// Created by Morris Swartz on 10/11/10.

// Build the template storage structure from several pieces
