/**
* SimpleScheduleBuilder is a {@link ScheduleBuilder}
* that defines strict/literal interval-based schedules for
* Triggers.
*
* Quartz provides a builder-style API for constructing scheduling-related
* entities via a Domain-Specific Language (DSL). The DSL can best be
* utilized through the usage of static imports of the methods on the classes
* TriggerBuilder, JobBuilder,
* DateBuilder, JobKey, TriggerKey
* and the various ScheduleBuilder implementations.
*
* Client code can then use the DSL to write code such as this:
*
* JobDetail job = newJob(MyJob.class)
* .withIdentity("myJob")
* .build();
*
* Trigger trigger = newTrigger()
* .withIdentity(triggerKey("myTrigger", "myTriggerGroup"))
* .withSchedule(simpleSchedule()
* .withIntervalInHours(1)
* .repeatForever())
* .startAt(futureDate(10, MINUTES))
* .build();
*
* scheduler.scheduleJob(job, trigger);
