Class Description

 BrRunsDb is a Db class which manages BrRun's with information
 extracted from the BRAHMS run database. It connects to the
 BRAHMS run database via the TSQLServer.  There are several
 ways for runs to be selected.  A single run can be selected
 using BrRunsDb::SelectRun(irun) where irun is the run to be
 selected.  Another way to select a group of runs is to use
 BrRunsDb::SelectRuns(time1,time2) where time1,2 are TDatime
 objects specifying time intervals for a list of runs to be
 selected.

 To get the runs, use BrRunsDb::GetRun(isel) which returns
 a BrRun object which was built in the SelectRun or SelectRuns
 methods.

 Example:
     BrRunsDb *runDb = new BrRunsDb("mysql://pii3.brahms.bnl.gov/RUNDB",
                                    "query","query-only");
     BrDbRun *run = runDb->GetRun("1554");

     run now contains all of the information in the run DB
     extracted from run 1554.

     Alternatively, one can use:
     TDatime time1(2000,6,27,0,0,0);
     TDatime time2(2000,6,28,0,0,0);
     TObjArray *runList = runDb->SelectRuns(Form("StartTime > %d and EndTime < %d",time1.Convert(),time2.Convert()));  //select all runs of 6/27/00

     Then to use them, use:
     Int_t numruns = runList->GetEntries();
     for(isel=0;isel<numruns;isel++) {
        BrRun *run = (BrRun*)runList->At(isel);
              .
              .
              .
           process this run
              .
              .
              .
        }
