//  SiPixelGenError.cc  Version 2.30
//
//  Object stores Lorentz widths, bias corrections, and errors for the Generic Algorithm
//
//  Created by Morris Swartz on 10/27/06.
//  Add some debugging messages. d.k. 5/14
//  Update for Phase 1 FPix, M.S. 1/15/17
//  V2.01 - Allow subdetector ID=5 for FPix R2P2, Fix error message
//  V2.10 - Update the variable size [SI_PIXEL_TEMPLATE_USE_BOOST] option so that it works with VI's enhancements
//  V2.20 - Add directory path selection to the ascii pushfile method
//  V2.21 - Move templateStore to the heap, fix variable name in pushfile()
//  V2.30 - Fix interpolation of IrradiationBias corrections
