Mon 29 Feb 2016 : drivers_for_path_directions.adb changed for added
  parameter in dobldobl_incfix_continuation.

Sat 27 Feb 2016 : updates in drivers_for_path_directions.adb for changes in
  increment-and-fix continuation in standard double precision.

Wed 10 Feb 2016 : added silent procedure to standard_vlprs_algorithm
  and improved the silent update in directions_of_standard_paths.adb.
  Did the same for the dobldobl and quaddobl versions.

Tue 12 Jan 2016 : small fix in directions_of_dobldobl_paths.ads and updated
  directions_of_quaddobl_paths.adb.
