The mechanism is the following:
1. You are interested in showing a set of model property, that you can
declare in the __properties__ member map.
2. You define one or more observers that observe one or more properties
you registered. When someone changes a property value the model notifies
the changing to each listening controller. The property-observer[s]
association is given by the implicit rule in observers method names: if
you want the model notified the changing event of the property 'p'
you must define the method called 'property_p_change_notification' in
each listening observer class.
Notice that tipically 'controllers' implement the observer pattern.
The notification method gets the
emitting model, the old value for the property and the new one.
Properties functionalities are automatically provided by the

class PropertyMeta (type):
"""This is a meta-class that provides auto-property support.
The idea is to allow programmers to define some properties which
will be automatically connected to auto-generated code which handles
access to those properties.
How can you use this meta-class?
First, '__metaclass__ = PropertyMeta' must be class member of the class
you want to make the automatic properties handling.
Second, '__properties__' must be a map containing the properties names
as keys, values will be initial values for properties.
That's all: after the instantiation, your class will contain all properties
you named inside '__properties__'. Each of them will be also associated
to a couple of automatically-generated functions which get and set the
property value inside a generated member variable.
About names: suppose the property is called 'x'. The generated variable
(which keeps the real value of the property x) is called _prop_x.
The getter is called get_prop_x(self), and the setter is called
'set_prop_x(self, value)'.
Customization:
The base implementation of getter is to return the value stored in the
variable associate to the property. The setter simply sets its value.
Programmers can override basic behaviour for getters or setters simply by
defining their getters and setters (see at the names convention above).
The customized function can lie everywhere in the user classes hierarchy.
Every overrided function will not be generated by the metaclass.
To supply your own methods is good for few methods, but can result in a
very unconfortable way for many methods. In this case you can extend
the meta-class, and override methods get_[gs]etter_source with your
implementation (this can be probably made better).
An example is provided in meta-class PropertyMetaVerbose below.
