/**  This class is a basic class to get the quantity of items.
  *  User processes the statistics raw data by deriving FbxStatistics class and overrides \c AddItem method.
  *  When overriding \c AddItem method, User must store item's name and item's count by pair which means
  *  The index of one item's name in array \c mItemName is the same as the index of this item's count in array \c mItemCount.
