//
// 1/10/06      mf, de  Created
//
// Changes:
//
//   1 - 3/22/06  mf  - in configure_dest()     
//      Repaired the fact that destination limits for categories
//      were not being effective:
//      a) use values from the destination specific default PSet
//         rather than the overall default PSet to set these
//      b) when an explicit value has been set - either by overall default or 
//         by a destination specific default PSet - set that limit or
//         timespan for that dest_ctrl via a "*" msgId.
