/**
* Overview of wallet database classes:
*
* - CDBEnv is an environment in which the database exists (has no analog in dbwrapper.h)
* - CWalletDBWrapper represents a wallet database (similar to CDBWrapper in dbwrapper.h)
* - CDB is a low-level database transaction (similar to CDBBatch in dbwrapper.h)
* - CWalletDB is a modifier object for the wallet, and encapsulates a database
* transaction as well as methods to act on the database (no analog in
* dbwrapper.h)
*
* The latter two are named confusingly, in contrast to what the names CDB
* and CWalletDB suggest they are transient transaction objects and don't
* represent the database itself.
