Интерфейс к SQLite

Пример использования:

    try
    {
        SQLiteInterface db;
        if( !db.connect("test.db") )
        {
            cerr << "db connect error: " << db.error() << endl;
            return 1;
        }
        
        stringstream q;
        q << "SELECT * from main_history";
        
        SQLiteResult r = db.query(q.str());
        if( !r )
        {
            cerr << "db connect error: " << db.error() << endl;
            return 1;
        }

        for( SQLiteResult::iterator it=r.begin(); it!=r.end(); it++ )
        {
            cout << "ROW: ";
            SQLiteResult::COL col(*it);
            for( SQLiteResult::COL::iterator cit = it->begin(); cit!=it->end(); cit++ )
                cout << as_string(cit) << "(" << as_double(cit) << ")  |  ";
            cout << endl;
        }

        db.close();
    }
    catch(Exception& ex)
    {
        cerr << "(test): " << ex << endl;
    }
    catch(...)
    {
        cerr << "(test): catch ..." << endl;
    }
