The dispatcher needs to know what the ID of a packet is to
do its job.  The idea is that instead of passing the ID and the packet 
separately,
the packet knows its own ID.  It is possible, though to replace the ID 
type with
std::string in the dispatcher and use std::string(typeid(packet).name())
avoiding the ID's entirely inside the dispatcher.
