// ----------------------------------------------------------------------
//
// ELdestControl  is a handle class whose purpose is to dispatch orders
//                from the framework to an ELdestination, without
//                allowing the framework to destruct that instance of the
//                destination (which would be a disasterous way to foul up).
//                The ELadministrator creates an ELdestControl handle
//                to its own copy whenever an ELdestination is attached.
//
// 7/5/98  mf   Created file.
// 6/16/99 jvr  Allows suppress/include options on destinations
// 7/2/99  jvr  Added separate/attachTime, Epilogue, and Serial options
// 6/7/00  web  Reflect consolidation of ELdestination/X; add
//      filterModule()
// 10/04/00 mf  add excludeModule()
// 01/15/00 mf  mods to give user control of line length
// 03/13/01 mf  mod to give user control of hex trigger and 
//      statisticsMap() method
// 04/04/01 mf  add ignoreMOdule and respondToModule
// 10/17/01 mf  add setTableLimit which had been omitted
// 10/18/01 mf  Corrected default in summary title =0 to empty string
//  6/23/03 mf  changeFile() and flush() 
//  6/19/08 mf  summaryForJobReport()
