/**
* The class KabAPI provides a public interface to access the
* users address database created using kab. The complete
* functionality regarding database operations provided by kab is
* available using an object of this class.
*
* The class is derived from the class KDialogBase, thus objects
* can be used as a KDE dialog where the user may select a person
* out of the entries in his personal database.
* The following code may be used to let the user select an address:
* \code
* KabAPI kabapi(this);
* if(dialog.init()!=KabAPI::NoError)
* {
* ... error handling
* }
* AddressBook::Entry entry;
* if(kabapi.exec())
* {
* if(!kabapi.getEntry(entry))
* {
* // ... the database is empty
* } else {
* // ... use the entry
* }
* }
* ...
* \endcode
* Some methods declared here return keys of entries. The keys are of the
* datatype KabKey. Every key
* is (of course) unique and identifying. If you store it, you can access
* the entry it represents with it. Be careful that the entry may have been
* deleted by another program instance meanwhile!
* <tt>Please be careful to test for the return code NotImplemented as
* long the kab API is not completely finished.</tt>
* @short The class KabAPI defines the API to access user address databases.
* @author Mirko Boehm <mirko@kde.org>
