                          PropertyAttribute

adds the property protocol to the parent instance.

The property protocol consists of the methods - setProperty(name, value), - getProperty(name, default=Undefined) - clearProperty(name) - hasProperty(name)

getProperty works like dict.get, except it will raise a KeyError without a default.

This is provided for user information and, to some extent, some DC-internal purposes.
