[Zope] Creating properties with a product.

[Daniel Rusch]

Take a look at the doc string in the class definition of PropertyManager. It states that:
An object may specify that it has one or more predefined
    properties, by specifying an _properties structure in its
    class::

      _properties=({'id':'title', 'type': 'string', 'mode': 'w'},
                   {'id':'color', 'type': 'string', 'mode': 'w'},
                   )

    The _properties structure is a sequence of dictionaries, where
    each dictionary represents a predefined property. Note that if a
    predefined property is defined in the _properties structure, you
    must provide an attribute with that name in your class or instance
    that contains the default value of the predefined property.

Also take a look at some of the other products out there that have properties and you will see how they handle them. Don't forget to update any properties you have added in your manage_edit member function for example: self._updateProperty('cool',cool)

Hope this helps,
