responses

At this point there is a big hole in COODBMS--responses. To date we've been using out, which should only be used for debugging.

Every action potentially can have a response. We also need to rework queries to use RoleML and have a similar mechanism for responses.

We can use the DRM for responses, adding to this model as needed to handle various types of responses. The top level of the responses will be the Responses element. Each action will have a responseId which will, when there is a response to that action, be used to name a element under the Responses element.

With this approach we will have the option of running COWDB as a separate process with multiple clients, passing the responses back to the client as XML.
