	Parameters:
		item:Any
			any object that can be recursively iterate
		children_parents_method:str
			name of the method that gets the children/parents item
			(default="children")
		delete_duplicates:bool=True
			Useful if you use flatten_all=True
			default=True)

		flatten_all:bool=False
			Returns all items as a flattened list
			default=False)

		normalize_children_list:bool=False
			Useful if you don't want to flatten the output and want the same length for
			every children list (e.g. for creating a DataFrame)
			(default=False)
	Returns:
		readyitems:list
