/**
* eGroupWare API loader
*
* Rewritten by RalfBecker @ outdoor - training . de to store the eGW enviroment
* ( egw - object and egw_info - array ) in a php - session and restore it from
* there instead of creating it completly new on each page - request .
* The enviroment gets now created by the egw - class
