Editing Nature's Aura recipes with CraftTweaker

A few notes that apply for most of the recipe types:

If you don't know how the CraftTweaker syntax works, read up on it first.
name is the name of a recipe, it can really be anything, but cannot clash with existing recipe names
IIngredient is any kind of ingredient, meaning either an OreDictionary entry or an item
IItemStack is an item
aura is the amount of Aura required and represents the total amount required for the completion of the recipe (for reference, 1,000,000 is the default amount of Aura present in the world and 2,000,000 is the amount that is required for the Environmental Eye's bar to fill up fully)
time is the time processes take in ticks
For most removal recipes, output is the output of the recipe that should be removed. All recipes with the given outupt will be removed.

mods.naturesaura.Altar.addRecipe(String name, IIngredient input, IItemStack output, IIngredient catalyst, int aura, int time)

catalyst is the catalyst block that is placed on one of the four corner blocks, can be null

mods.naturesaura.Altar.removeRecipe(IItemStack output)

mods.naturesaura.AnimalSpawner.addRecipe(String name, String entity, int aura, int time, IIngredient[] ingredients)

mods.naturesaura.AnimalSpawner.removeRecipe(String name)

entity is the registry name of the entity whose spawning recipe should be removed

mods.naturesaura.Offering.addRecipe(String name, IIngredient input, int inputAmount, IIngredient startItem, IItemStack output)

inputAmount is the amount of items required for the input. Note that this means that the amount of the input variable is ignored
startItem is the item required to start the offering, should pretty much always be naturesaura:calling_spirit

mods.naturesaura.Offering.removeRecipe(IItemStack output)

mods.naturesaura.TreeRitual.addRecipe(String name, IIngredient saplingType, IItemStack result, int time, IIngredient[] items)

saplingType is an item representation of the sapling that needs to be placed and grown into a tree
items are the items that need to be placed on the wooden stands
