/**
 * TDbCronModule class.
 *
 * TDbCronModule does everything that TCronModule does but stores the tasks and
 * persistent data in its own database table.
 *
 * The TDbCronModule allows for adding, updating, and removing tasks from the
 * application and shell.  It can log executing tasks to the table as well.
 *
 * There are log maintenance methods and {@see \Prado\Util\Cron\TDbCronCleanLogTask} for cleaning
 * the cron logs.
 *
 * Runtime Tasks can be added for execution onEndRequest.  Singleton tasks can
 * be added to TDbCronModule, and scheduled to execute during Runtime at
 * onEndRequest.  Then if it does not execute onEndRequest, then the next
 * shell cron will execute the task.  This could occur if the user presses stop
 * before the page completes.
