/**
* Reads/writes account data from/to a user branch in the {@code All-Users} repository.
*
* This is the low-level API for account creation and account updates. Most callers should use
* {@link AccountsUpdate} for creating and updating accounts.
*
*
This class can read/write account properties, preferences (general, diff and edit preferences)
* and project watches.
*
*
The following files are read/written:
*
*
* - 'account.config': Contains the account properties. Parsing and writing it is delegated to
* {@link AccountProperties}.
*
- 'preferences.config': Contains the preferences. Parsing and writing it is delegated to
* {@link StoredPreferences}.
*
- 'account.config': Contains the project watches. Parsing and writing it is delegated to
* {@link ProjectWatches}.
*
*
* The commit date of the first commit on the user branch is used as registration date of the
* account. The first commit may be an empty commit (since all config files are optional).
