+located within the specified area. Area can be x1/y1-x2/y2 square,

 This is useful for maps that are split into many buildings, such as all 
 the "*_in" maps, due to all the shops and houses.
 
+Examples:
+	// return players in area npc area on current map.
+	.@num = getareausers();
+	// return players in square (1, 1) - (10, 10)
+	.@num = "players: " + getareausers(1, 1, 10, 10);
