//===== Description: ==================================================================================
//= Referral System Working:
/*
	Player A : Old player (Invited player B and C)
	Player B and C : New comers
	
 1: As Player B and Player C logs in, they need to find npc
	"Referral Npc" and must Sign with NPC by choosing option
	"- My Friend Called me!" and Enter the exact name of his
	friend and then complete process by choosing option
	"Complete the process".
 2: The Player will be asked to Relog to Start with the System.
 3: As he relog, a timer will start attaching to player and
	it will run till he completes his todays work, i.e Play/
	Stay online for 5 Hours at your server.(as per below con-
	figuration, can be changed according to needs).
	********************************************************\
	  set $@hourstoplay, 5;	// No. of hours to play everyday.
	\*******************************************************
 4: But, the reward wont be given just yet, the NPC will do
	constant checking, to see whether players B and C are
	active, for at least *days( Depends on you. ).
	Being active means, any(or) all of these;
		* Logs in and plays atleast X (won't mention this)
   		  hours a day.
		* The npc keeps checking IP's Everytime the players
		  logs in, ( You can set the no. of octets you want
		  to check of ip-address ) 
		Eg; Referrals starting with first 3 octets being the 
		same, ex: 204.152.10.25 and 204.152.10.75, won't count
		and it will dispbottom the warning.
 5: If they meet all those requirements, the inviter, will be
	rewared with some items.
