[WIP] QUARKS-13: Start over Quarks when the JVM crashes (Linux)
Simple mechanism to restart a Quarks application if the JVM running Quarks
terminates unexpectedly:
- Sample application which simulates a JVM crash after processing N tuples
- Script which checks whether the Quarks JVM is still running, otherwise
it restarts the Quarks sample app
- Cron entry which runs the script every mnute
- Readme providing setup instructions

> Thinking of a mechanism which restarts the Quarks application if the JVM
> running Quarks hangs or closes unexpectedly. These options come to mind:
> - Write a script which checks for the pid of the jvm process running Quarks
> and restarts Quarks if the pid is not there. Run the script every minute
> using a cron job.
> - Setup Quarks app to run as a Linux service. Use inittab or systemd to
> manage Linux services and have options to restart a managed process
> automatically.
> There is also the hardware option. Embedded platforms frequently rely on
> watchdog hardware that resets it automatically if software stops periodically
> signalling the hardware that it is still alive.
> Anyone have any thoughts on this?
