// ELstatistics is a subclass of ELdestination representing the
//      provided statistics (for summary) keeping.
//
// 7/8/98 mf    Created file.
// 7/2/99 jvr   Added noTerminationSummary() function
// 12/20/99 mf  Added virtual destructor.
// 6/7/00 web   Reflect consolidation of ELdestination/X; consolidate
//      ELstatistics/X.
// 6/14/00 web  Declare classes before granting friendship.
// 10/4/00 mf   Add filterModule() and excludeModule()
// 1/15/00 mf   line length control: changed ELoutputLineLen to
//              the base class lineLen (no longer static const)
// 3/13/01 mf   statisticsMap()
//  4/4/01 mf   Removed moduleOfInterest and moduleToExclude, in favor
//              of using base class method.
// 1/17/06 mf   summary() for use in MessageLogger
// 8/16/07 mf   noteGroupedCategory(cat) to support grouping of modules in
//      specified categories.  Also, a static vector of such categories.
// 6/19/08 mf   summaryForJobReport() for use in CMS framework
//
