Class MarshalledEvent

Class to contain an event marshalled into the wire form.

Typical uses:

App reads data according to a wire protocol that matches
the protocol used here (pkt size + pickling). (This is a flaw
in the design of this, but as this is an attempt to partially
encapsulate something that's currently not at all encapsulated
it is sufficient if used with care):

myData = (get the data somehow)
me = MarshalledEvent()
me.SetData(myData)
myEvent = me.GetEvent()

App has an event that it wants to send to multiple file handles:

me = MarshalledEvent()
me.SetEvent(myEvent)
for fh in handles():
    me.Write(fh)
