Wildcards in config argument

[danielhundhausen]

I think it would be nice to be able to pass wildcards (*) in the config command line argument. This would enable the user to produce e.g. all electron related plots with only one command:

python src/plotter.py cfg_plots/V29/electron*

Or if technically possible even all versions of all electron plots:

python src/plotter.py cfg_plots/V*/electron*

I used a bash script for now for f in ls *.yaml; do python .. $f; done, but of course built-in functionality would be good ;)
