A tiny library to make it easier to run multiple top-level goroutines in the same application:

• runner provides an abstraction that handles shutdown signal and wait group (so that goroutines don't need to care about it)
• job represents logic that is run inside top-level goroutine. There are 2 jobs that I use most often and therefore provided by default:
  • recurring job
    • run work periodically (using Go ticker)
    • an example can be found here. This example spins up 2 goroutines that run ticker periodically. 2nd job has some custom clean up logic
  • blocking job
    • run work and block waiting for it to complete (.e.g. a http server)
    • an example can be found here. This example runs a recurring job in 1 goroutine and a http server in the other. The http server has custom clean up logic
  • when a work implements CleanUp interface from job, both recurring and blocking jobs above will execute clean up logic when they receive shutdown signal
