Create functions (doDeleteSingleTimeBlock, doDeleteSingleReservation, doCreateQueuedMessages) to generalize process of deleting scheduled reservations and created queued messages; Add 'getEqGroup' method to Time_Blocks and Reservations classes to more easily fetch a group; Add method 'doDelete()' to 'db_linked' class to easily set flag of any object as deleted (flag_delete=TRUE); Provide documentation to all failure points within ajax_schedule.php within the 'notes' element of the  associative array (hash); Generalize doCreateQueuedMessages and move to schedule.class;
