Version 1.134 2001-04-23 (MT)
-------------
- Implemented a method
  	ColumnData * Column::rowData(
		unsigned long	rowNumber,
		AccessMode	accessMode=AsParent )
  which can be used to access either Fixed or Variable length column data.
  + Implemented cxx test harness cxxtest/fixvarcolumn.cc which shows how an
  example of how to use it.
- Table::seek() now works correctly in high memory mode.
- Optimsed the way in which the DAL checks the format of FITS files.
- Implemented a c++ dal utility class TableSeeker:
  + to use it do
  	#include <dal_utilities.h>
  + Implemented cxx test harness dalcomtest/tableseeker.cc, which shows an
    example of how to use it.
  + Implemented the f90 type:
	type TableSeekerT
		integer, pointer :: ptr
	end type
  + Implemented the following f90 dal modules/functions/subroutines:
 
	! Functions/Subroutines related to the TableSeeker class
	function newTableSeeker( table )
		type(TableT), intent(in) :: table

		type(TableSeekerT) :: newTableSeeker

		call error( "", errorMessage )

	end function newTableSeeker

	subroutine releaseTableSeeker( tableSeeker ) ! accessible through release interface
		type(TableSeekerT), intent(in) :: tableSeeker

		call error( "", errorMessage )

	end subroutine releaseTableSeeker

	function tableSeekerNext( tableSeeker ) ! accessible through interface next
		type(TableSeekerT), intent(in) :: tableSeeker
		
		logical :: tableSeekerNext

		call error( "", errorMessage )

	end function tableSeekerNext

	function fromTableSeeker( tableSeeker ) ! accessible through interface from
		type(TableSeekerT), intent(in) :: tableSeeker

		integer :: fromTableSeeker

		call error( "", errorMessage )

	end function fromTableSeeker

	function countTableSeeker( tableSeeker ) ! accessible through interface count
		type(TableSeekerT), intent(in) :: tableSeeker

		integer :: countTableSeeker

		call error( "", errorMessage )

	end function countTableSeeker

	subroutine resetTableSeeker( tableSeeker ) ! accessible through interface reset
		type(TableSeekerT), intent(in) :: tableSeeker

		call error( "", errorMessage )

	end subroutine resetTableSeeker

  + Implemented fortran90 test harness f90test/tableseeker.f90, which shows an
    example of how to use it.
