    Query SELinux policy users.

    Parameter:
    policy            The policy to query.

    Keyword Parameters/Class attributes:
    name            The user name to match.
    name_regex      If true, regular expression matching
                    will be used on the user names.
    roles           The attribute to match.
    roles_equal     If true, only types with role sets
                    that are equal to the criteria will
                    match.  Otherwise, any intersection
                    will match.
    roles_regex     If true, regular expression matching
                    will be used on the role names instead
                    of set logic.
    level           The criteria to match the user's default level.
    level_dom       If true, the criteria will match if it dominates
                    the user's default level.
    level_domby     If true, the criteria will match if it is dominated
                    by the user's default level.
    level_incomp    If true, the criteria will match if it is incomparable
                    to the user's default level.
    range_          The criteria to match the user's range.
    range_subset    If true, the criteria will match if it is a subset
                    of the user's range.
    range_overlap   If true, the criteria will match if it overlaps
                    any of the user's range.
    range_superset  If true, the criteria will match if it is a superset
                    of the user's range.
    range_proper    If true, use proper superset/subset operations.
                    No effect if not using set operations.
