+ Defines the PTPIP  device class generic bulk container dataset. This is used to hold all the PTPIP packets except data packets
+ by changing the payload. It holds the packet length and packet type as its first two elements, after which it holds a payload, 
+ which will change, depending on the kind of PTPIPpacket. For eg this could be a request packet, a cancel packet or a start
+ data packet. 
+
+ Eg :  the structure of the class while getting a request can be as follows
+ 1. packet length	4 bytes
+ 2. packet size		4 bytes
+ 3. payload = request packet.
