Review comment:
I don't think we should implicitly create a topic for the output. I think
it makes more sense for the the user to explicitly specify it. The user might
even be more confused if he or she can submit a function without a output
topic. He or she might not even know what the default output topic name will
be.
If we really want to create a default output topic automatically for the
function, lets at least check that the function is set to return a non-void
type. There is no point to create automatically creating an output topic if
the function is set to return void
