Using file picker instead of text field

[SylvainDe]

It could be interesting to have the choice to use filer picker instead of text field.

I have started to work on such a change but I haven't got time to make this perfect and shiny.

Here is what I have done so far

It will be a great idea in my opinion. But perhaps keep both options text field and filer picker, but perhaps is too much.

@RandyHandy Keeping both is actually a pretty good idea. Tricky, but good. A file picker alone wouldn't convey much information, so I'll be nice to also have a place to display what the user chooses. This would also allow the possibility of your drag and drop idea (issue #28).

Kind of a standard setup, like:

+--------------------------------------------------+
|                                                  |
|    +----------------------------+  +--------+    |
|    | C:/some_dir/my_file.txt    |  | Browse |    |
|    +----------------------------+  +--------+    |
|                                                  |
|                                                  |
|                                                  |
+--------------------------------------------------+

You could do this automatically in some cases, if the types of the entries are from pathlib or path.py.

maybe metavar would be the place to set this?

parser.add_argument("-i", dest="filename", required=True,
    help="input file with two matrices", metavar="FILE")

Done!
