/**

* This was written on jCrete 2015 on a LeJOS session by Steven Chin.

*

* We were given the task to build a lego and do something cool with it.

* We built a pretty large tank and remote-controlled it via wi-fi with

* simple socket commands.

*

* For more info, go to https://mihail.stoynov.com/?p=2909

*

* This is a mock server for testing if you don't have a lego at hand.
