+Simple example of a synchronized swarm choreography using the High level

 The swarm takes off and flies a synchronous choreography before landing.
 The take-of is relative to the start position but the Goto are absolute.

 It aims at documenting how to use the High Level Commander together with
 the Swarm class to achieve synchronous sequences.
