[Corona] Corona explore endpoint and web-interface?

Yep, DELETE requests can take in a query :) (https://github.com/marklogic/Corona/wiki/Deleting-Documents).
On the surface it might seem a bit unusual, but in practice it's pretty handy. For example, many times I don't know what the URI of a document is. If I'd like to delete a document where the id attribute equals "123456", that's very easy to satisfy with a query. It also makes it easy to delete multiple documents in one request (e.g.: delete all of the emails with a given thread id).
I couldn't really speak to how feasible it would be to get good error messages from ml-rest-lib. But I'm going to include Norm Walsh (author of the library) on this thread and see if he has any thoughts on what options we have as users and if any changes to the library would be reasonable.
