Throws if: - Symbols do not match or contracts do not match

  static function neq(a: ExtendedSymbol, b: ExtendedSymbol): bool

Checks that symbols and contracts are not equal for objects

Throws if: - Symbols are equal and contracts are equal

  static function lt(a: ExtendedSymbol, b: ExtendedSymbol): bool

Checks that the symbol a is less than b and contract a is less than b

Throws if: - Symbol a is greater or equal b or contract a is greater or equal b
