/*
* the class manages reminders. here reminders are reffered to as spirit
* bullets.
*
* loadReminder(String) : this func has several roles :
*
* 1 to input a reminder. examples : remind me to eat at 11:30 remind me to
* exercise at 18:00 on sunday
*
* 2 to forget the reminders : clear reminders
*
* 3 reveal the next reminder compared to the time
*
* 4 recycle a reminder. normally a reminder gets deleted after it is fired up
* unless you loadBullet("thank you"), this will reload the reminder.
*
* 5 attempting to add a reminder beyond the msgLim will result in the output :
* too many reminders.
*
* loadBullet :
*
* this outputs the requested query or the reminder if its time has come. it
* uses a timegate to prevent a reminder from firing up more than once.
