/**
 * A Reader is an acutal event stream source for sensor events, and it may be
 * comprised of one or more Sensors. However, each sensor will have one and only
 * one DeviceProfile. This will faciliate multiple sensors being combined to create 
 * a physical event stream. This is a bit different that logical readers, as thesse 
 * devices are combind at a much lower level (DeviceManager) as opposed to ALE Serivice.
 * This is a specific requirement for the ALE Specification.
