 *         The goal of this class is to make registering the inventory renders
 *         for your Items/Blocks a much simpler and easier process.
 * 
 *         You must call this at the post initialization stage on the clientside
 *         only.
 * 
 *         If you pass a Block through here that uses the default ItemBlock, you
 *         should specify a custom name.
