The augmentdb module defines AugmentDatabase.
An AugmentDatabase is derived from ~pyrseas.database.Database. It contains two "dictionary" objects.
One is the Dicts container from its parent class. The db Dicts object, defines the database schemas, including their tables and other objects, by querying the system catalogs.
The second container is an AugDicts object. The adb AugDicts object specifies the schemas to be augmented and the augmenter configuration objects. The latter objects may be supplied either by other Augmenter modules or from the 'augmenter' configuration tree on the aug_map supplied to the apply method.
