hilbert/qrhandler repository overview

NOTE: this is currently just a demo.

It currently:

• overtakes a specified input device (USB HID Keyboard) like AT Translated Set 2 keyboard (my laptop keyboard),
• grabs it exclusively and runs action.sh on each ENTER'ed string as a main loop.

In turn action.sh:

• displays a message and
• takes a screenshot with scrot.

Just pass the device name or ID (displayed by xinput) as a single string argument to qrhandler.sh
