    '''
    Check a whitelist and/or blacklist to see if the value matches it.

    value
        The item to check the whitelist and/or blacklist against.

    whitelist
        The list of items that are white-listed. If ``value`` is found
        in the whitelist, then the function returns ``True``. Otherwise,
        it returns ``False``.

    blacklist
        The list of items that are black-listed. If ``value`` is found
        in the blacklist, then the function returns ``False``. Otherwise,
        it returns ``True``.

    If both a whitelist and a blacklist are provided, value membership
    in the blacklist will be examined first. If the value is not found
    in the blacklist, then the whitelist is checked. If the value isn't
    found in the whitelist, the function returns ``False``.
