SETools descriptors.
These classes override how a class's attributes are get/set/deleted.
This is how the @property decorator works.
See https://docs.python.org/3/howto/descriptor.html
for more details.

Single item criteria descriptor.
Keyword Parameters:
name_regex The name of instance's regex setting attribute;
used as name_regex below. If unset,
regular expressions will never be used.
lookup_function The name of the SELinuxPolicy lookup function,
e.g. lookup_type or lookup_boolean.
default_value The default value of the criteria. The default
is None.
enum_class The class of enumeration which supports a
lookup class method.
Read-only instance attribute use (obj parameter):
policy The instance of SELinuxPolicy
name_regex This attribute is read to determine if
the criteria should be looked up or
compiled into a regex. If the attribute
does not exist, False is assumed.
