                  @capability Adding a preference option, HOWTO example.
                  @abstract this example will help you understand how the email preferences work.
                  @author Angles
                  @discussion email preferences, like many other eGW preference items, do not have a 
                  Database table devoted only to email preferences. If there were such a Database table, its fields 
                  would describe a schema similar to the one we are about to study. Email prefs are stored in the eGW 
                  preferences table, which is shared by many apps and has the charactoristics of a dynamic data store, i.e. 
                  we can add, remove, or change email preference details without having to alter the Database table itself. 
                  This can make programming easier, but it also can present a chalange if your app has many preferences, 
                  which may have a complicted tree-like hierarchy.
                  Low level preference functiond are handled by the pgpGW api. The data itself is stored in the database as 
                  a serialized array using the php functions serialize and unserialize.
                  We can gain the flexibility of a rich preference data handling system by doing some work up front. The 
                  work in question here is an array based schema hard coded in this function, yet similar schema definitions 
                  could exist in an XML file, as the concept is very similar.
                  We use an associaltive array (i,e. not a simple numbered array) to hold our schema data,
                  @example This is a how-to  example for adding an email preference item, saving it to the prefs DB table, 
                  retieving the pref, and using it in code. This DocSubTopic deals with adding an email preference item, 
                  using pref item "icon theme" as an example. A Step-by-Step example is provided with explanation,
                  (1) copy an  existing preference item to use as a template for your new preference item.
                  (2) replace in the schema with your information, as such:
                  *id*        The "Unique ID" of this pref item. The pref DB uses this like a UID. 
                  *type*      [ exists| user_string | known_string ]
                  *widget*    [ checkbox | textbox | textarea | combobox | passwordbox ]
                  *accts_usage*     [ default, extra_accounts ]
                  *write_props*     [ empty_string_ok | password, hidden, encrypted, empty_no_delete | no_db_defang ]
                  *lang_blurb*      description displayed to the user on the preferences page.
                  *init_default*    --possible tokens are--
                                    string            [any_string]  ex. 'string,new_old'
                                    set_or_not  [set|not_set]  ex.  'set_or_not,not_set'
                                    function          [string_will_be_eval'd] ex. "function,$this->sub_default_userid($accountid)"
                                    init_no_fill      we will not fill this item during initialization (ex. a password)
                                    varEVAL           [string_to_eval] ex. "$GLOBALS['phpgw_info']['server']['mail_server']"
                  *values*          Array of values available to the user, "key" => "value" , used with combobox widgets.
                  *long_desc* Long help, detained description of the option displayed to the user as "long help".
                  (3) Your are done. The preference is now part of email preferences. It will bedisplayed on the preferences 
                  page, saved and read from the preferences DB, it will have the default value you specified unless the user
