// ----------------------------------------------------------------------
//
// ELlimitsTable is a class holding two maps:  One listing various
//               limits associated with each id, and one counting occurrences
//               and tracking latest times of each type of extended-id
//               (id + severity + module + subroutine + process).
//               In addition, there is a table by severity of defaults,
//               and a single wildcard default limit.
//
// The fundamental operation is
//
//      bool add( const ELextendedID & )
//
// which checks if the extended id is in the main map.  If it is not, it
// looks for the specified limit (by id, then severity, then wildcard) and
// cretes an entry in the main map for this extended id.  The count is
// incremented, (perhaps zero-ed first if the timespan was exceeded) and
// checked against its limit.  If the limit is not exceeded, OR is exceeded
// by 2**N times the limit, this returns true.
//
// Limits of -1 mean react to this error always.
// Limits of 0 in the auxilliary defaults indicate that the corresponding
// limit was not specified.
//
// 7/6/98 mf    Created file.
// 6/7/00 web   Reflect consolidation of ELdestination/X
// 6/14/00 web  Declare classes before granting friendship.
// 6/15/01 mf   Grant friendship to ELoutput so that faithful copying of
//              ELoutput destinations becomes possible.
// 5/16/06 mf   Added wildcardInterval member, and severityIntervals
