Detailed Description

Create / access multi purpose counters.

Counter Creation:

// counter creation:
ICounterSvc::CountObject obj = svc->create("AlgName","NumExecuted",0);
 obj++;
 obj += 10;
 ICounterSvc::Counter*  m_counter = obj.counter();
 // ICounterSvc::Counter*  m_counter = obj ; ///< the same
 ICounterSvc::Counter* m_counter = 0;
 if ( svc->create("AlgName","NumExecuted",0, m_counter).isSuccess() )
 {
    CountObject obj(m_counter);
    obj++;
 }

Counter access:

ICounterSvc::Counter* m_counter = svc->get("AlgName","NumExecuted");
if ( m_counter )  {....}
// or:
try {
  ICounterSvc::CountObject obj(svc->get("AlgName","NumExecuted"));
  obj++;
}
catch(std::invalid_argument e)  {
   ...handle exception ...
}

name	[IN] Counter name
initial_value	[IN] Initial counter value
refpCounter	[OUT] Reference to store pointer to counter.

Returns: StatusCode indicating failure or success.
