===========================================================

Step 0
------

.. sourcecode:: python

    from employee import Employee

    class PyEmployee(object):
        def __init__(self, **kwargs):
            self.e = Employee()
            for k, v in kwargs.items():
                setattr(self, k, v)

        given = property(
            lambda self: self.e.GetGivenName(),
            lambda self, v: self.e.SetGivenName(v),
        )
        family = property(
            lambda self: self.e.GetFamilyName(),
            lambda self, v: self.e.SetFamilyName(v),
        )
        birth = property(
            lambda self: self.e.GetDateOfBirth(),
            lambda self, v: self.e.SetDateOfBirth(v),
        )

    e = PyEmployee(given='Feihong', family='Hsu', birth='2007-11-15')

    print e.given, e.e.GetGivenName()

    e.given = 'Horatio'     # change given name through the property
    print e.given, e.e.GetGivenName()

Expected output::

    Feihong Feihong
    Horatio Horatio
