"""Example Script for sending Signals
This Script sends Signals with Different Colors over the Bridge.The resends parameter 
specifies how often a package is resend. 
A lower value can lead to package loss. The resends_gap parameter 
specifies how long the artificial delay behind every transmission is. Usually this 
value can be set to 0 if the resends value is sufficiently high.
The default values are set to values that are moste likely to work on most Systems. 
It´s also possible to adjust which stones are targeted by changing the status value. 
The Status values for available Gravitrax Power stones can be found in the 
gravitrax_constants file.
