   * @brief Allows filtering by a priori surface point radius sigma
   *
   * This class allows the user to filter control points and control measures
   * by a priori surface point radius sigma. This allows the user to make a
   * list of control points that are less than or greater than a certain
   * a priori surface point radius sigma.
