/**

|
* 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
