-// * declaring an option:
-//    struct Algo1_CostFunction {
-//      virtual float cost(int x) const { return x; }
-//      virtual ~Algo1_CostFunction() {}
-//    };
-//
-// * accessing an option:
-//    config.Get<Algo1_CostFunction>().cost(value);
-//
-// * setting an option:
-//    struct SqrCost : Algo1_CostFunction {
-//      virtual float cost(int x) const { return x*x; }
-//    };
-//    config.Set<Algo1_CostFunction>(new SqrCost());
-//
-// Note: This class is thread-compatible (like STL containers).
