/******************************************************************
* Explanation of the scheduler									*
*																 *
* Here are the scheduler DB fields, and what they are used for :  *
*  - sched_id : Unique ID. Before calling the file responsible	*
*	for the event, the variable $sched_var_id will be set to	 *
*	this value, so the called file can modify the triggering	 *
*	scheduler entry if it needs to.							  *
*																 *
*  - is_loop : Set this to 'Y' if you want the event to be looped	*
*	endlessly. If this value is set to 'Y', the 'spawn' field is *
*	not used.													*
*																 *
*  - loop_count : If you want your event to be run a certain number *
*	of times only, set this to the number of times. For this to	 *
*	work, loop must be set to 'N'. When the event has been run   *
*	spawn number of times, it is deleted from the scheduler.	 *
*																 *
*  - ticks_left : Used internally by the scheduler. It represents *
*	the number of mins elapsed since the last call. ALWAYS set   *
*	this to 0 when scheduling a new event.					   *
*																 *
*  - ticks_full : This is the interval in minutes between		 *
*	different runs of your event. Set this to the frenquency	 *
*	you wish the event to happen. For example, if you want your  *
*	event to be run every three minutes, set this to 3.		  *
*																 *
*  - file : This is the file that will be called when an event	*
*	has been trigerred.										  *
*																 *
*  - extra_info : This is a text variable that can be used to	 *
*	store any extra information concerning the event triggered.  *
*	It will be made available to the called file through the	 *
*	variable $sched_var_extrainfo.							   *
*																 *
* If you are including files in your trigger file, it is important*
* to use include_once() instead of include(), as your file might  *
* be called multiple times in a single execution. If you need to  *
* define functions, you can put them in your own				  *
* include file, with an include statement. THEY CANNOT BE		 *
* DEFINED IN YOUR MAIN FILE BODY. This would cause PHP to issue a *
* multiple function declaration error.							*
*																 *
* End of scheduler explanation									*
