7  * Retrieves data for a master/detail report in one shot,
8  * storing every detail recordset in the master recordset,
9  * using the method setChildrenRecordset(). Then overrides
10  * getDetail() to return the detail recordset using the method
11  * getChildrenRecordset() of the master recordset. Interesting
12  * too is the way this class reuses the superclass implementations
13  * of service() and getDetail() to minimize the code required
14  * to accomplish its task.
