Services
Services could be anything that wants to associate itself with the DFFML API.
For instance there is a HTTP service in the works that will allow access to DFFML APIs similarly to the way the CLI does, over an HTTP interface.
Services could also be any helper utilities, such as the dev service. Which
helps developers who want to create new Models, Sources, Operations, or
Services. It also helps developers hack on DFFML itself.
