/**
 * Receives android.intent.action.EVENT_REMINDER intents and handles
 * event reminders.  The intent URI specifies an alert id in the
 * CalendarAlerts database table.  This class also receives the
 * BOOT_COMPLETED intent so that it can add a status bar notification
 * if there are Calendar event alarms that have not been dismissed.
 * It also receives the TIME_CHANGED action so that it can fire off
 * snoozed alarms that have become ready.  The real work is done in
 * the AlertService class.
 *
 * To trigger this code after pushing the apk to device:
 * adb shell am broadcast -a "android.intent.action.EVENT_REMINDER"
