Christmas tree path

Python
A simple script to fly a Crazyflie with Flow Deck in a path shaped as a Christmas tree
"""
This script does a scripted flight path using the MotionCommander class.
The path is shaped as a Christmas tree.

Connects to the crazyflie at `URI` and runs a
sequence. Change the URI variable to your Crazyflie configuration.
