95Meta-class for initializing Model classes properties.
96
97Used for initializing Properties defined in the context of a model.
98By using a meta-class much of the configuration of a Property
99descriptor becomes implicit. By using this meta-class, descriptors
100that are of class Model are notified about which class they
101belong to and what attribute they are associated with and can
102do appropriate initialization via __property_config__.
103
104Duplicate properties are not permitted.

256Initializes a class that might have property definitions.
257
258This method is called when a class is created with the PropertiedClass
259meta-class.
260
261Loads all properties for this model and its base classes in to a dictionary
262for easy reflection via the 'properties' method.
263
264Configures each property defined in the new class.
265
266Duplicate properties, either defined in the new class or defined separately
267in two base classes are not permitted.
268
269Properties may not assigned to names which are in the list of
270_RESERVED_WORDS. It is still possible to store a property using a reserved
271word in the datastore by using the 'name' keyword argument to the Property
272constructor.
273
274Args:
275 cls: Class being initialized.
276 name: Name of new class.
277 bases: Base classes of new class.
278 dct: Dictionary of new definitions for class.
279
280Raises:
281 DuplicatePropertyError when a property is duplicated either in the new
282 class or separately in two base classes.
283 ReservedWordError when a property is given a name that is in the list of
284 reserved words, attributes of Model and names of the form '__.*__'.
