Response Object Hierarchy

[robmoffat]

Sometimes, we want to send responses that aren't templated. This currently isn't possible.

Maybe one implementation of Response should be TemplatedResponse or ChatWorkflowResponse?

[robmoffat]

Could you choose the template by using something like this:

<messageML templatename="normal.fml">askldjdlsk</messageML>

or, TemplatedResponse class which contains the template name

This might be nice if the user wants to return lots of different icons, too

public DataResponse(Workflow wf, Addressable stream, EntityJson data, String name, String instructions) {

this is an anti-pattern: name and instructions are too specific and never really fit what you want to do.
