Recipe Builder 
Just like other recipe types, the Altar of Birthing also uses a recipe builder.
Don't know what a builder is? Check the builder info page out.
Recipe Builder
- Create the Recipe Builder. groovy- mods.naturesaura.spawning.recipeBuilder()
- IngredientList<IIngredient>. Sets the item inputs of the recipe. Requires greater than or equal to 1.groovy- input(IIngredient) input(IIngredient...) input(Collection<IIngredient>)
- ItemStackList. Sets the item outputs of the recipe. Requires exactly 1.groovy- output(ItemStack) output(ItemStack...) output(Collection<ItemStack>)
- int. Sets how much aura the recipe drains from the environment. Requires greater than or equal to 1. (Default- 0).groovy- aura(int)
- int. Sets the time the recipe takes to complete. Requires greater than or equal to 1. (Default- 0).groovy- time(int)
- ResourceLocation. Sets the entity spawned. Requires not null.groovy- entity(EntityEntry) entity(ResourceLocation)
- First validates the builder, returning - nulland outputting errors to the log file if the validation failed, then registers the builder and returns the registered object. (returns- nullor- de.ellpeck.naturesaura.api.recipes.AnimalSpawnerRecipe).groovy- register()
Example
mods.naturesaura.spawning.recipeBuilder()
    .name('demo')
    .input(item('minecraft:clay'))
    .entity(entity('minecraft:bat'))
    .aura(100)
    .time(100)
    .register()
mods.naturesaura.spawning.recipeBuilder()
    .name(resource('example:demo'))
    .input(item('minecraft:mutton'))
    .entity(entity('minecraft:wolf'))
    .aura(30)
    .time(5)
    .register()
mods.naturesaura.spawning.recipeBuilder()
    .input(item('minecraft:bone'), item('minecraft:dye:15') * 4)
    .entity(resource('minecraft:skeleton'))
    .aura(10)
    .time(10)
    .register()Removing Recipes 
- Removes all Altar of Birthing recipes that summon the given entity: groovy- mods.naturesaura.spawning.removeByEntity(EntityEntry)
- Removes all Altar of Birthing recipes that summon the given entity: groovy- mods.naturesaura.spawning.removeByEntity(ResourceLocation)
- Removes all recipes that match the given input: groovy- mods.naturesaura.spawning.removeByInput(IIngredient)
- Removes the Altar of Birthing recipe with the given name: groovy- mods.naturesaura.spawning.removeByName(ResourceLocation)

Example
mods.naturesaura.spawning.removeByEntity(entity('minecraft:polar_bear'))
mods.naturesaura.spawning.removeByEntity(resource('minecraft:cave_spider'))
mods.naturesaura.spawning.removeByInput(item('minecraft:bone'))
mods.naturesaura.spawning.removeByName(resource('naturesaura:cow'))
mods.naturesaura.spawning.removeAll()Getting the value of recipes 
- Iterates through every entry in the registry, with the ability to call remove on any element to remove it: groovy- mods.naturesaura.spawning.streamRecipes()
