Starting to serialize and deserialize peered data to be transferred
over the network.

I'm pretty sure that there will be a bug transferring peered lists of
lists/maps of lists/etc.  I may have to change the code so that peered
lists of lists/maps keep track of their references so that can know
when to replace reference with a new one and when to reuse reference.
See fixme at line 175 of waldoNetworkSerializer.py.  Also, clearly,
add more test cases.
Added some very basic test code to ensure that serialization and deserialization of a peered number works properly.
