PacketHandler
~~~~~~~~~~~~~

The basic packet handling event/callbackcase
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First, initialize the packet handler
    >>> from pyogp.lib.base.message.message_handler import MessageHandler
    >>> message_handler = MessageHandler()

How about a mock callback handler
    >>> def callback(packet): print packet

    >>> onStartPingCheck_received = message_handler.register("StartPingCheck")
    >>> onStartPingCheck_received.subscribe(callback)

Stage a packet
    >>> from pyogp.lib.base.message.message import Message
    >>> packet = Message('StartPingCheck')

Fire the event, it returns a packet
Unpossible to include this in the test, the memory ref keeps changing
But, you get the idea...
    event_data = message_handler.handle(packet)
    <pyogp.lib.base.message.message.Message object at 0x14da450>
