   * @brief Allows filtering by a control measure's line
   *
   * This class allows the user to filter control measures by their line (i.e.
   * which line they are positioned at in the image). This allows the user to
   * make a list of control measures that are too close to the edge of an
   * image after pointreg adjustment.
