Usage Example:

Arguments:
-d : Specify a recording directory.
This could have one or many recordings contained within it.
We will recurse into the dir.
-s : Specify path to Pupil Player user_settings file to use last used vizualization settings.
-e : Specify export directory if you dont what the export saved within each recording dir.
-c : If you dont use the player settings file, we use a default circle.
You can specify color to be used
