/**
* Generalized SQL Storage Object with build in custom field support
*
*
* This class allows to display, search, order and filter by custom fields simply by replacing so_sql
* by it and adding custom field widgets to the eTemplates of an applications.
* by it and adding custom field widgets to the eTemplates of an applications.
* It's inspired by the code from Klaus Leithoff, which does the same thing limited to addressbook.
*
* The schema of the custom fields table should be like (the lenght of the cf name is nowhere enfored and
* varies throughout eGW from 40-255, the value column from varchar(255) to longtext!):
*
*
* 'egw_app_extra' => array(
* 'fd' => array(
* 'prefix_id' => array('type' => 'int','precision' => '4','nullable' => False),
