Idea: Recipe Types

My idea is to have the ability to make recipe types. It would be spilt into parts:

• Element - the element used to make the custom recipe type. It would have a text for the name, optional template, input slots, output slots, and field for custom gui.
• Recipe Element - editing the recipe element to be able to use custom types.
• GUI - the ability to link a gui with a recipe type whether it is Minecraft or custom.
• Procedures a. the ability to use procedures with element types. b. Procedures like get ingredient int of recipe _ , get result of recipe _, unlock recipe _ and get recipe of itemstack.
