Implement the **Strategy Choice table**. 

     class StrategyChoice 
     { 
     public: 
       // a function that creates a strategy instance by strategy Name 
       typedef function<shared_ptr<Strategy>(const Name&)> StrategyCreator; 
      
       // constructor 
       StrategyChoice(NameTree& nameTree, shared_ptr<Strategy> defaultStrategy); 
    
       // install strategy 
       // Strategy::getName() gives its strategyName, which must be unique 
       bool install(shared_ptr<Strategy> strategy); const StrategyCreator& strategyCreator, const Name& defaultStrategyName); 
      
       // set strategy of prefix to be strategyName 
       bool insert(const Name& prefix, const Name& strategyName); 
      
       // make prefix to inherit strategy from its parent 
       // not allowed for root prefix (ndn:/) 
       void erase(const Name& prefix); 
      
       // get strategy Name of prefix (exact match) 
       shared_ptr<Name> shared_ptr<const Name> get(const Name& prefix); 
      
       // get effective strategy for prefix 
       Strategy& shared_ptr<Strategy> findEffectiveStrategy(const Name& prefix); 
      
       // get effective strategy for pitEntry (NameTree shortcut) 
       Strategy& shared_ptr<Strategy> findEffectiveStrategy(const pit::Entry& pitEntry); 
     };
