--[[ Consumables Helper by Skeem

	 a friend requested it so I made a simple one
	 might turn into a more complicated script later
	 I've been using this in most of my plugins
	
	 Features
	 - Uses Health Pots (1 at the time with % in menu)
	 - Uses Mana Pots (1 at the time with % in menu)
	 - Recalling Checks to not waste pots if backing
	
	 Changelog:
	 0.1 : Beta Release
	 0.2 : Added Recalling check
	 
	 TODO:
	 - Add flask
	 - Add Items such as Zhonyas
	 - Add Red Pot
