/**
* Provides a quartz job that reviews and generates all recurring tasks.
* The quartz scheduler is restarted if this file is edited so startDelay will then delay again.
* The execute method is called once every repeatInterval (in milliseconds).
* With concurrent=false the next job is blocked until the previous job completes.
* Apparently we need a hibernate session otherwise we get a LazyInitializationException, default is true but we specify it to be sure.
