- Maps a network predicate:
- * `{net, {:nick, nickname}}`
- * `{net, {:account, account}}`
- * `{net, {:mask, user@host}}`
- to an unique identifier, that can be shared over multiple networks.
-
- If a predicate cannot be found for an existing account, a new account will be made in the database.
-
- To link two existing accounts from different network onto a different one, a merge operation is provided.
