It allows:
-to register new crafting types, with register_new_craft_type(name,setf,getf)
name if the name of the crafting type, setf is a function that will be called when registering a craft, that should store the recipe somewhere, and getf if called when calling minetest.get_craft_result, and should return something like get_craft_result (a table with the new item, and a table for the replacements)
-to allow or not to register a crafting recipe. For that, use the minetest.register_can_register_craft: it should return true if craft can be registered, or false if you want to cancel craft. For now, it is the only way to remove a crafting definition from default mod.
-to be called when a crafting recipe is registered, by using minetest.register_on_register_craft. This can be useful for mods like crafting guides which would like to access other recipes types than default ones.
