-----------------------------------

{{cd lang/py && ant build test}} passes all the tests with this patch applied, AFAICT.

> The {{avro.protocol.Protocol}}, {{avro.protocol.Message}}, and various classes in {{avro.schema}} all support a {{to_json}} method which renders the data in Python generics (easily renderable to json).
> These methods all take a required {{names}} argument (of type {{avro.schema.Names}} which stores state representing what types have already been rendered.
> For debugging -- and for other uses of the schema -- it is helpful if the {{names}} argument is optional.  When it is not provided, each method should construct an empty {{schema.Names}} object internally. {{to_json}} thus can be invoked without argument to get the relevant rendering of the current schema in isolation.
> Patch to be attached.
