// Implementation of BlindTools' offset blinding method
// A RooUnblindOffset object is a real valued function
// object, constructed from a blind value holder and a 
// set of unblinding parameters. When supplied to a PDF
// in lieu of a regular parameter, the blind value holder
// supplied to the unblinder objects will in a fit be minimized 
// to blind value corresponding to the actual minimum of the
// parameter. The transformation is chosen such that the
// the error on the blind parameters is indentical to that
// of the unblind parameter
