class Symbology(SymbologyObject):
	"""
	/symbology

	Positional arguments:
		No arguments are required.

	Optional arguments:
		All arguments are inherited from SymbologyObject

	Attributes:
		object : str . Returns the type of object it is. (card, error, etc)
		has_more : bool . True if there are more pages to the object.
		data : list . A list of all data returned.
		data_length : int . The length of the data returned.

		The following require an integer as an arg, which acts as a tuple.
		symbol_symbol(num) : str . The plaintext symbol, usually written with curly braces.
		symbol_loose_variant(num) : str . The alternate version of the symbol, without curly braces.
		symbol_transposable(num): bool . True if it's possibly to write the symbol backwards.
		symbol_represents_mana(num): bool . True if this is a mana symbol.
		symbol_cmc(num): float . The total converted mana cost of the symbol.
		symbol_appears_in_mana_costs(num): bool . True if the symbol appears on the mana cost of any card.
		symbol_funny(num): bool . True if the symbol is featured on any funny cards.
		symbol_colors(num): float . An array of all colors in the given symbol.

	Example usage:
		>>> symbol = scrython.symbology.Symbology()
