Richard Async usecase.

Richard has applications that take a long time to process their data. They are compute-intensive. This includes building phylogenetic trees, and analyzing genotype information to build population structures.

Currently, these applications are run as command-line jobs. It would be ideal if they could be exposed as services, so that they can be used within pipelines, or launched from off-site. However, the long run-time of these applications prevents naive synchronous methods for exposing them.
