/**
 * Information about a single user.
 * <p>
 * A user may have multiple identities they can use to login to Gerrit (see
 * {@link AccountExternalId}), but in such cases they always map back to a
 * single Account entity.
 *<p>
 * Entities "owned" by an Account (that is, their primary key contains the
 * {@link Account.Id} key as part of their key structure):
 * <ul>
 * <li>{@link AccountAgreement}: any record of the user's acceptance of a
 * predefined {@link ContributorAgreement}. Multiple records indicate
 * potentially multiple agreements, especially if agreements must be retired and
 * replaced with new agreements.</li>
 *
 * <li>{@link AccountExternalId}: OpenID identities and email addresses known to
 * be registered to this user. Multiple records can exist when the user has more
 * than one public identity, such as a work and a personal email address.</li>
 *
 * <li>{@link AccountGroupMember}: membership of the user in a specific human
 * managed {@link AccountGroup}. Multiple records can exist when the user is a
 * member of more than one group.</li>
 *
 * <li>{@link AccountProjectWatch}: user's email settings related to a specific
 * {@link Project}. One record per project the user is interested in tracking.</li>
 *
 * <li>{@link AccountSshKey}: user's public SSH keys, for authentication through
 * the internal SSH daemon. One record per SSH key uploaded by the user, keys
 * are checked in random order until a match is found.</li>
 *
 * <li>{@link StarredChange}: user has starred the change, tracking
 * notifications of updates on that change, or just book-marking it for faster
 * future reference. One record per starred change.</li>
 *
 * <li>{@link AccountDiffPreference}: user's preferences for rendering side-to-side
 * and unified diff</li>
 *
 * </ul>
