This provides the class-method behaviour that Ruby's JSON
support expects but that we don't provide.

+# A simple module to provide consistency between how we use JSON and how 
+# ruby expects it to be used.  Basically, we don't want to require
+# that the sender specify a class.
+#  Ruby wants everyone to provide a 'json_class' field, and the JSON support
+# requires such a field to track the class down.  Because we use our URL to
+# figure out what class we're working on, we don't need that, and we don't want
+# our consumers and producers to need to know anything about our internals.
