Improvements:
Timers are used for measuring the perfomance of current operation or any part of
code, and provide amount of calls of operation.
Timers are used for debugging purposes and optimising perfomance.

More information you can find in the corresponding .cdl files (see list of new
classes in the "List of modified entities").

Example (can use in the Users Guide):
Using timers in XSDRAWIGES.cxx and IGESBRep_Reader.cxx for
analysis performance command "igesbrep":

XSDRAWIGES.cxx
  ...
  #include <MoniTool_Timer.hxx>
  #include <MoniTool_TimerSentry.hxx>
  ...
  MoniTool_Timer::ClearTimers();
  ...
  MoniTool_TimerSentry MTS("IGES_LoadFile");
  Standard_Integer status = Reader.LoadFile(fnom.ToCString());
  MTS.Stop();
  ...
  MoniTool_Timer::DumpTimers(cout);
  return;
                                                                                
                        
IGESBRep_Reader.cxx
  ...
  #include <MoniTool_TimerSentry.hxx>
  ...
  Standard_Integer nb = theModel->NbEntities();
  ...
  for (Standard_Integer i=1; i<=nb; i++) {
    MoniTool_TimerSentry MTS("IGESToBRep_Transfer");
    ...
    try {
      TP.Transfer(ent);
      shape = TransferBRep::ShapeResult (theProc,ent);
    }
    ...
  }

Result DumpTimer() after translation file:

 TIMER: IGES_LoadFile Elapsed: 1.0 sec, CPU User: 0.9 sec, CPU
Sys: 0.0 sec, hits: 1
 TIMER: IGESToBRep_Transfer Elapsed: 14.5 sec, CPU User: 4.4 sec, CPU
Sys: 0.1 sec, hits: 1311

Modified entities:
New classes:
MoniTool_Timer
  Provides convenient service on global timers accessed by string name,
  mostly aimed for debugging purposes.
  As an instance, envelopes the OSD_Timer to have it as Handle
  As a tool, supports static map of timers and provides static methods
  to easily access them.
MoniTool_TimerSentry
  A tool to facilitate using MoniTool_Timer functionality by
  automatically ensuring consistency of start/stop actions.
  When instance of TimerSentry is created, a timer with corresponding
  name is started, when instance is deleted, timer stops.

Internal - not for Reference Doc:
MoniTool_MTHasher
  The auxiliary class provides hash code for mapping timers.
TagsNo tags attached.
