   A better way to print a log messages would be using a version of   
   DEBUG_PRINT macro that print the line number, which would be implemented as:   
   inline void debugPrint( const std::string& text, const int atLine )   
   {   
   #ifndef NDEBUG   
     std::cout << text << "Happened at line number" << atLine << std::endl;   
   #endif   
   }   
      
   Now, it would be even better to print the file where it happened :   
   inline void debugPrint( const std::string& text, const int atLine, const   
   std::string file )   
   {   
   #ifndef NDEBUG   
     std::cout << text << "Happened at line number" << atLine << " in the   
   file " << file << std::endl;   
   #endif   
   }   
      
   This can be done using next macro:   
   #define DEBUG_PRINT(x) std::cout << text << "Happened at line number" <<   
   __LINE__ << " in the file " << __FILE__ << std::endl;
