Overview of wallet database classes:

• WalletBatch is an abstract modifier object for the wallet database, and encapsulates a database batch update as well as methods to act on the database. It should be agnostic to the database implementation.

The following classes are implementation specific:

• BerkeleyEnvironment is an environment in which the database exists.
• BerkeleyDatabase represents a wallet database.
• BerkeleyBatch is a low-level database batch update.
