 * \brief This class contains the various fit options which are independent of the fit model itself.
 *
 * The user has the choice between several different fit options
 * - 1d or 2d fit
 * - use t instead theta
 * - acceptance correction
 * - detector smearing
 * - detector smearing parametrizations
 * - fit ranges
 * - estimator type
 * - estimator options
 *
 * The fields can only be set by the user within the #PndLmdFitFacade class, to
 * avoid further alterations of the variables after a their intial setting.
