Editable query results

[osmanmesutozcan]

Query results should be editable.

Main challenge is to come up with a unified way to handle commits.

Best way to handle this could be to give connector author a way to get notified when a cell is edited.

Author can collect the updates until it they are committed and save when it is updated.

But this way would create a confusing dataconnector interface.

Maybe instead we can create another interface to wrap query result edits. With each edit we can ask connector author to update the wrap. and wrap interface can have a build method to generate a
publishable query.
