/**
 * Uniquely identifies a {@link JobDetail}.
 * 
 * <p>Keys are composed of both a name and group, and the name must be unique
 * within the group.  If only a group is specified then the default group
 * name will be used.</p> 
 *
 * <p>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
 * <code>TriggerBuilder</code>, <code>JobBuilder</code>, 
 * <code>DateBuilder</code>, <code>JobKey</code>, <code>TriggerKey</code> 
 * and the various <code>ScheduleBuilder</code> implementations.</p>
 * 
 * <p>Client code can then use the DSL to write code such as this:</p>
 * <pre>
 *         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);
 * <pre>
 *  
 * 
 * @see Job
 * @see Key#DEFAULT_GROUP
