// <b> The Publish-Subscribe Application Packet </b>
//
// Pub-sub packet sent by Publish and Subscribe Ethernet Applications. Contains
// the FID of the message, in order to be forwarded to the correct subscribers, 
// the type of the packet (e.g. ), the length of the scope (according the the 8 
// byte PURSUIT_ID_LEN) and finally the whole Information Item ID (IIID). This 
// IIID includes the scope and the ID of the Information Item sent, according 
// to the C++ class, InformationItem. If the size of the PSEtherApp message is 
// greater than ~1400, it will consist of several Ethernet frames. The last field
// of the message is optional and can be used for detection of palse positives.
// It is suggested that it is controlled by a global variable.
