A job runner for executing scheduled or ad-hoc tasks asynchronously from HTTP requests.
It adds a couple of features on top of the cron package to make it play nicely with Revel:
1. Protection against job panics. (They print to ERROR instead of take down the process)
2. (Optional) Limit on the number of jobs that may run simulatenously, to limit resource consumption.
3. (Optional) Protection against multiple instances of a single job running concurrently. If one execution runs into the next, the next will be queued.
4. Cron expressions may be defined in app.conf and are reusable across jobs.
5. Job status reporting.
const DefaultJobPoolSize = 10
const UnNamed = "(unnamed)"

Run the given job right now.
type Func func()
Callers can use jobs.Func to wrap a raw func. (Copying the type to this package makes it more visible)
