Added IoT SensorTag demo to tradeshow
iot-sensortag folder added. This is project originally from consultacy repo, moved to here. It's a cross-platform app that shown multiple data values from TI CC2650 SensorTag. Change-Id: I648464ed9a8253e5069bc6fd59e8b92128b60adc Reviewed-by: Maurice Kalinowski <maurice.kalinowski@qt.io>
