/**
 * API - accounts
 *
 * This class uses a backend class (at them moment SQL or LDAP) and implements some
 * caching on to top of the backend functions:
 *
 * a) instance-wide account-data cache queried by account_id including also members(hips)
 *    implemented by self::cache_read($account_id) and self::cache_invalidate($account_ids)
 *
 * b) session based cache for search, split_accounts and name2id
 *    implemented by self::setup_cache() and self::cache_invalidate()
 *
 * The backend only implements the read, save, delete, name2id and the {set_}members{hips} methods.
 * The account class implements all other (eg. name2id, id2name) functions on top of these.
 *
 * read and search return timestamps (account_(created|modified|lastlogin) in server-time!
