response handler that builds an OPeNDAP DDX object
A request 'get ddx for <def_name>;' will be handled by this response handler. Given a definition name it determines what containers are to be used to build the OPeNDAP DDX response object that includes attribute information found in a DAS object and data definitions found in a DDS object. It also knows how to transmit the DDX response object using the specified transmitter object in the transmit method.

executes the command 'get ddx for def_name;'
For each container in the specified definition go to the request handler for that container and have it first add to the OPeNDAP DDS response object. Once the DDS object has been filled in, repeat the process but this time for the OPeNDAP DAS response object. Then add the attributes from the DAS object to the DDS object.

return the current response object
Returns the current response object, null if one has not yet been created. The response handler maintains ownership of the response object.

replaces the current response object with the specified one, returning the current response object
This method is used to replace the response object with a new one, for example if during aggregation a new response object is built from the current response object.
The caller of set_response_object now owns the returned response object. The new response object is now owned by the response object.

transmit the response object built by the execute command
If a response object was built then transmit it using the send_ddx method on the specified transmitter object.
