Fixed argparse for fedsd

[erlingrj]

The docs are not up-to-date, fedsd doesnt work with fedsd *.lft, you have to do fedsd -r rti.lft -f fed1.lft fed2.lft.

This fixes the argparse setup so that the command line parsing works properly. Previously it turned the list of federate lfts into a double list [[lft1, fft2, ...,]] which crashed the rest of the script

The docs are not up-to-date, fedsd doesn't work with fedsd *.lft, you have to do fedsd -r rti.lft -f fed1.lft fed2.lft.

In the last update, fedsd does not work anymore with fedsd *.lft, but one needs to simply call fedsd instead. The README.md file (under util/tracing/visualization) was updated accordingly. It says:

Once the federation stopped executing, running `fedsd` will operate on all the `.lft` files in the current directory:

and

It is also possible to operate on specific files. In such a case, run `fedsd` with `-r` flag to provide the RTI trace file, and `-f` flag to provide the list of federate trace files. Both arguments are optional.

Actually, I didn't see any value in explicitly saying *.lft, if we need to use all local files.
Does this make sense?

Apologies for the overlook. Thanks for the fix!

LGTM.

I see! This is the handbook PR.

Commit 728e725 fixes some typos, while Commit 9ea185a adjuts the README file contents with this commit.
