    A ``format`` property checker.

    JSON Schema does not mandate that the ``format`` property actually do any
    validation. If validation is desired however, instances of this class can
    be hooked into validators to enable format validation.

    :class:`FormatChecker` objects always return ``True`` when asked about
    formats that they do not know how to validate.

    To check a custom format using a function that takes an instance and
    returns a ``bool``, use the :meth:`FormatChecker.checks` or
    :meth:`FormatChecker.cls_checks` decorators.

    Arguments:

        formats (iterable):

            The known formats to validate. This argument can be used to
            limit which formats will be used during validation.

        Register a decorated function as validating a new format.

        Arguments:

            format (str):

                The format that the decorated function will check.

            raises (Exception):

                The exception(s) raised by the decorated function when
                an invalid instance is found.

                The exception object will be accessible as the
                :attr:`ValidationError.cause` attribute of the resulting
                validation error.

        Check whether the instance conforms to the given format.

        Arguments:

            instance (any primitive type, i.e. str, number, bool):

                The instance to check

            format (str):

                The format that instance should conform to


        Raises:

            :exc:`FormatError` if instance does not conform to ``format``
