Workflow implemented -- July 29

Tools that implement multiple operations should also respond to the workflow parameter in the extended TRAPI schema. This allows external callers, such as the workflow runner or another ARA to make a series of calls to compose operations provided by different tools into a complete workflow.

@dkoslicki @edeutsch can you provide links here to aid in implementation? i.e. the specific form of the workflow specification?

[edeutsch]

I don't have anything specific at this point, but maybe a diff between our ARAX OpenAPI YAML without and with the operations stuff would be easiest for everyone. It sure would have for me!

We'll also have the TRAPI 1.2 template that will contain most of it.

At what point do we decide that we have enough that we should people: here, implement this?
At the Arch demo that @cbizon is planning?
If we're kinda stable by then, I suggest the diff as a show-and-tell item.
