RF: make the grid point tests work again
RF: make the grid point tests work again

Broke with e972cbca. After testing that the grid does the right thing using the
values before transformation:

    // temporarily add the targets
    //std::vector <double> best (3);
    //best[1] = 1/.5;
    //best[0] = -0.0*best[1];
    //best[2] = 0.05;

    //std::vector <double> second (3);
    //second[1] = 1/.5;
    //second[0] = -0.5*best[1];
    //second[2] = 0.05;

    //gridpoints.push_back(best);
    //gridpoints.push_back(second);

We convinced ourselves that it does indeed work as expected.
