[Dart-users] updates to DART subversion repository

[Nancy Collins]

hello dart-users,

i've committed 3 sets of code changes to the dart subversion
repository in the last week.  the most significant one just went in
today.  it's an update to the main filter program, the smoother_mod,
and obs_model_mod, required to make the smoother work correctly.

it also adds a lot more tracing messages.  you can turn them on by
adding trace_execution = .true. to your &filter_nml in input.nml.
when you update, you will need to get a new set of files from all
these dirs:

 filter, smoother, obs_model, perfect_model_obs, and integrate

i also updated the obs_sequence directory to patch a hole which
could allow someone to interactively create an obs_sequence file
with the observations out of time order.  this is no longer possible
and the obs_sequence_tool will now test for this when processing
obs_sequence files and warn you if you indeed have this situation.

and finally, i made a cosmetic change to all the mkmf_filter and
mkmf_wakeup_filter files to allow both -mpi and -nompi.  nompi
was always the default but it's nice to be able to explicitly say so
if you choose.  (the quickbuild.csh scripts already allowed -mpi
and -nompi.)   these changes have no dependencies and can be
updated on a dir by dir basis.

as always, i've tested but if you see anything unusual, please
contact me?

thanks,
nancy
