"""
Simple description of a member in the return value ``dict``.
This class controls both the type of object being returned by
a command as well as how the output will be displayed.
For example, this class defines two return results: an entry
and a value.
>>> from ipalib import crud, output
>>> class user(crud.Update):
...
... has_output = (
... output.Entry('result'),
... output.value,
... )
The order of the values in has_output controls the order of output.
If you have values that you don't want to be printed then add
``'no_display'`` to flags.
The difference between ``'no_display'`` and ``'no_output'`` is
that ``'no_output'`` will prevent a Param value from being returned
at all. ``'no_display'`` will cause the API to return a value, it
simply won't be displayed to the user. This is so some things may
be returned that while not interesting to us, but may be to others.
