class HSlowPar: public HParSet

_HADES_CLASS_DESCRIPTION

   HSlowPar

   Container to keep slowcontrol summary informations for a bunch of
   channels (mean, rm, min, max values) for a list of runs.

   //##################################################

   HOWTO FILL the container in a macro:

   HSlowPar p("HSlowPar_test","HSlowPar_test");

   HSlowChan c;
   c.mean = 1750.;
   c.rms  = 5;
   c.min  = 1740.;
   c.max  = 1760.;
   c.print()

   p.setChannel(runID,"HV_MDC_example",&c,kFALSE); // set channel in macro to write to ROOT/ASCII
   ..... more channels and runIDs
   p.makeChannelList(kTRUE); // kTRUE = sort, call this function after all channels have been set
                             // needed to create the list of channels

   //--------------------------------------------------
   For the init from ORACLE the list of channels has to be
   set before and the Partition specified (all runs for the day
   of the runID used for init will be added automatically):

   HSlowPar p("HSlowPar_test","HSlowPar_test");
   p->addToChannelList(""HV_MDC_example""); // add a channel name
   p->setPartition("online);  // during beam time
                              // (default is offline) after slow control
                              // summaries are moved to final tables
   //--------------------------------------------------

   HOWTO USE the container:

   HSlowPar* p = (HSlowPar*)gHades->getRuntimeDb()->getConatiner("SlowPar");
   Double_t values[4];
   p->getChannel(runid,"HV_MDC_example",&c);        // get Channel with name for a given runID
   p->getChannel(runid,"HV_MDC_example",values);    // get Channel with name for a given runID

   p->printParam();                         // print container content
   p->printChannel(runID,"HV_MDC_example"); // print a single channel
   Bool_t ok = p->findRunId(runID);         // is this runID inside ?
   Int_t first,last;
   p->getRangeRunID(first,last);            // get first and last runID inside the container
   Int_t n = p->getNRunIDs();               // get the number runIDs inside the container
   TList* list = p->getChannelList();       // get the list of channel names
