The asynciojobs library adds dependency management to asyncio-based scenarios.
It allows to create and run schedulers, where jobs are coroutines or other asyncio-friendly programs, whose dependencies are directed acyclic graphs (DAGs).
Schedulers can be nested, i.e. a scheduler can be used as a job; this features allows functions to be written, that return pieces of scenarios.
