Fix errors in SQL and EqGroup class, and create more Unit tests; Found 2 SQL errors ('reservation.class'); Identify failure of SQL errors by creating 4 new unit tests ('TestOfReservation.class'); Fix 2 SQL errors ('reservation.class'); Create 1 new unit test ('SchedulesCreateTest'); Fix newly found bugs in 'eq_group.class' in which ->loadManagers() and ->loadConsumers() so that these methods each return an associate array (hash) of user objects that are both direct user managers and indirect inst_group user managers. Note: Formerly, these methods were each returning an array of user objects AND inst_group objects, which would cause an error when attempting to send queued email messages using loadCommPrefs(); Create new Unit tests in 'TestOfEqGroup.class' to support the above modification;
