// 4. You must install the switch (NEXA) in TelldusCenter, give it a name (eks: NEXA1) and unit nr 1, and run the learning process.
// 5. Copy  TelldusCore.dll to the .exe directory of this program.
// 6. Compile and run this example.
// 8. You should now be able to paly with the switch, turn it on and off.
