// <b> The Ethernet Publisher Application </b>
//
// This publisher application needed in every publisher node in a publish
// subscribe network. It works just over the MAC layer, and this is why it
// is necessary to implement MAC encapsulation. This module extends the 
// BasePSApp module and adds the necessary functionality. For instance, 
// it is able only to publish new or existing Information Items, kept in 
// the Information item table.
