/**

* generalized linking between entries of eGroupware apps - BO layer
|
|
*
|
|
* This class is the SO-layer of the links
|
|
*
|
|
* Links have two ends each pointing to an entry, each entry is a double:
|
|
* - app app-name or directory-name of an egw application, eg. 'infolog'
|
|
* - id this is the id, eg. an integer or a tupple like '0:INBOX:1234'
|
|
*
|
|
* All vars passed to this class get correct escaped to prevent query insertion.
