Added the lastCall construct: if the stopping condition becomes true in eoCheckPoint,

a method called lastCall is called for everything contained in that checkpoint
      (stats, updaters and monitors). This can be extremely useful
      - for stateSavers (see below)
      - for monitoring things like rates of success of operators, where what you
        are interested in is the final result only.
Added of course a virtual method lastCall that does nothing by default in classes
      eoBaseStat, eoBaseSortedStat, eoUpdater and eoMonitor
Added a boolean to control the save of the state in method eoCountedStateSaver::lastCall
      so you can ask that the state is saved at final population, whatever happens.
      I also added the corresponding constructor to take this into account.
