deleting project and/or quotes via api

This is really frustrating.

I'm writing integration tests for my xtrf frontend interface UI.

I'd like to build up a client, add a project or quote to it, delete the project/quote and delete the client, e.g., cleanup.

There's no provision for deleting a project or quote via the api, and I can't delete the client as there is now a project or quote attached to it.

What's up with this?
