/**
 * Quick little guide on how to use this thing:
 * <p>
 * The method fabricate() returns an ItemStack.
 * <p>
 * 
 * For creating a legendary item, do:
 * <p>
 * RareItemFactory.begin(ItemType.LEGENDARY).setLegendary(AlligatorsTooth.class)
 * .fabricate();
 * <p>
 * 
 * For creating a Flaming Jagged Diamond Sword of Conquering, simply do:
 * <p>
 * RareItemFactory.begin(ItemType.WEAPON).setType(Material.DIAMOND_SWORD).
 * setSuperPrefix(FlamingAttribute.class).setPrefix(JaggedAttribute.class).
 * setSuffix(ConqueringAttribute.class).fabricate();
