implements ContextListener, SensorValueListener
    A WIFI-based context example test application. This example creates a WifiContext named "work wifi". The example WifiContext is used to detect whether a wifi given ssid is currently connected. Further, the example shows how to receive updates to the contexts active value. For example context type and sensor type implementations:
