// ELoutput is a subclass of ELdestination representing the standard
//      provided destination.
//
// 7/8/98 mf    Created file.
// 6/17/99 jvr  Made output format options available for ELdestControl only
// 7/2/99 jvr   Added separate/attachTime, Epilogue, and Serial options
// 2/22/00 mf   Changed myDetX to myOutputX (to avoid future puzzlement!)
//      and added ELoutput(ox) to cacilitate inherited classes.
// 6/7/00 web   Consolidated ELoutput/X; add filterModule()
// 6/14/00 web  Declare classes before granting friendship; remove using
// 10/4/00 mf   add excludeModule()
//  4/4/01 mf   Removed moduleOfInterest and moduleToExclude, in favor
//      of using base class method.
//  6/23/03 mf  changeFile(), flush() 
//  6/11/07 mf  changed default for emitAtStart to false
