// ELlimitsTable.cc
//
// History:
//   7/6/98     mf      Created
//   6/10/99    jvr     Corrected initialization for severityLimits and
//                      timespans to -1 instead of 0.
//   6/17/99    jvr     setLimit(id,n) works w/ setTimespan(sev||"*",n)
//                      and setTimespan(id,n) w/ setLimit(sev||"*",n)
//   6/15/00    web     using -> USING
//  11/01/01    web     Fixed mixed-type comparisons
//   5/18/06    mf      setInterval
//  11/2/07     mf      add:  Changed ivl = wildcardLimit to wildcardInterval.
//                      Probably moot and never reached, but a clear correction.
//  9/29/10     mf,ql   Fix savanah bug 65284 where two messages of same
//                      category but different severity, if limits were not
//                      take from category, first severity sets the limit
//                      for both of those xid's.
