``KeysValidator``
-----------------

.. class:: KeysValidator(keys, strict=False, messages=None)

    Validates that the given keys are contained in the value. If ``strict`` is
    ``True``, then it also checks that there are no other keys present.

    The ``messages`` passed should be a dict containing the keys
    ``missing_keys`` and/or ``extra_keys``.

    .. note::
        Note that this checks only for the existence of a given key, not that
        the value of a key is non-empty.
