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.

Useless since commit d95e4619.

Useless since at least commit bff41cdd.

Useless since commit 8e6ce479.

The motivation is to be able to create the files `*traj*.json` for
only a component of the graph, so that `plot_traj.py` can plot the
trajectories in a single component, with different colors for
different trajectories.

The inpuy file has been re-created after commit 62ac3c9b.

To function `plot_single_traj`.

To function `plot_single_traj`.

Instead of storing it in the repository.

This should have been removed in commit 311c0598.

Remove timings from inside function `create_traj_list`.

Move function `create_traj_list` to a separate file.

Preparing for an independent script.
