//  Member:     CCliRotHintTable::GetIndicator
//
//  Synopsis:   Get whether indicator for hash entry is set
//
//  Arguments:  [dwOffset] - offset we are looking for
//
//  Returns:    TRUE - entry is set
//              FALSE - entry is not set
//
//  Algorithm:  If array has not been initialized, then bind to the SCM's
//              shared memory. Then check if the offset into the table is
//              set.
