This is the result of a student project to develop a new paparazzi center based on Python/Qt.
See http://wiki.paparazziuav.org/wiki/Paparazzi_Center/Evolutions for the main idea and development process.
It can be tested by running the main paparazzi launcher with the -python option. I more convenient way might be added later.
This PR is mostly a way to not loose this work, and other people are encourage to improve it in many aspects (HMI, functionalities, ...).
