Replace call to nml_filter by open_copy_data_file
(dont know why it hasnt always been that way in the first place).

12     c o This routine initialises the calendar according to the user
13     c specifications in "data.calendar".

15     c started: Christian Eckert eckert@mit.edu 30-Jun-1999
16     c
17     c changed: Christian Eckert eckert@mit.edu 29-Dec-1999
18     c
19     c - restructured the original version in order to have a
20     c better interface to the MITgcmUV.
21     c
22     c Christian Eckert eckert@mit.edu 10-Jan-2000
23     c
24     c - Modified namelist input. The data file is first copied
25     c to scrunit1 with the comment lines being left out.
26     c After this, scrunit1 is used to read the namelist data.
27     c
28     c Christian Eckert eckert@mit.edu 19-Jan-2000
29     c
30     c - Changed the role of the routine arguments. Chris Hill
31     c proposed to make the calendar less "invasive". The tool
32     c now assumes that the MITgcmUV already provides an ade-
33     c quate set of time stepping parameters. The calendar
34     c only associates a date with the given starttime of the
35     c numerical model. startdate corresponds to zero start-
36     c time. So, given niter0 or startdate .ne. zero the actual
37     c startdate of the current integration is shifted by the
38     c time interval correponding to niter0, startdate respec-
39     c tively.

41     c Christian Eckert eckert@mit.edu 03-Feb-2000
