Add argument SHPC-dir to script `inst_eddies_Aviso.py`. We want to be
able to run `inst_eddies_Aviso` in parallel for several slices. Since
we write `used_config_nml.txt` to the current directory, we need to
run the parallel instances from different directories. So the current
directory cannot always be the directory containing the SHPC to be
appended to.

Add argument `SHPC_dir` to function `loop_inst_eddies`. We want to be
able to run `loop_inst_eddies` in parallel for several slices. Since
we write `used_config_nml.txt` to the current directory, we need to
run the parallel instances from different directories. So the current
directory cannot always be the directory containing the SHPC to be
appended to.

We are trying to simplify the logic in program `inst_eddies`. Also,
the program `inst_eddies` should not write `used_config_nml.txt` to
the top level of the SHPC directory since several instances could run
in parallel for several slices. So we are leaving it as a task for a
script over `inst_eddies` to create `used_config_nml.txt` at the top
level of the SHPC directory.

Do not try to read `used_config_nml.txt`. We are reverting commit
d9a67386, trying to simplify the logic in program `inst_eddies`. We
consider that using a single configuration for several runs of
`inst_eddies` is the problem of a script over `inst_eddies`, not the
problem of `inst_eddies`. Drawback: we write again
`used_config_nml.txt` in several runs of `inst_eddies`, but this is
not important.

We want to be able to run `inst_eddies` from a directory other than
the directory containing the SHPC to be appended to. Preparing to
write `grid_nml.txt` and `used_config_nml.txt` in the current
directory. To be able to do this in parallel for several slices, we
need to be running in different directories.

Makes more sense.

So the user can get the usage message more easily.

In program `examine_eddy`.

Change order of command line arguments of program
`examine_eddy`. Preparing to allow a variable number of NetCDF file
arguments.

Do not always specify uv-file when it is the same as ssh-file.

Instead of reading command line arguments in procedure `input_ssh`,
read them outside and pass file names to `input_ssh`. This allows
`input_ssh` to be called by programs with different number of command
line arguments, in different positions. Preparing to make the
specification of uv-file optional.

Reverting part of commit c4410682. We want to extend the program to a
non-uniform or non longitude-latitude grid. Checking equality of whole
longitude and latitude arrays, one or two-dimensional, seems a little
bit too much.

It is now the same as test `Draw_component`.

Advantages: no need to provide the JSON file on the command line;
single loop on nodes.

Keep trajectory lists inside dictionaries, indexed by trajectory
number, instead of lists. This way, we can keep the trajectory numbers
when we work on part of the graph, for example in a component.
