Re: NTC utility doesn't want to play

Ok I found what was wrong. The stream was'nt being reset after reading 
the model in the first file.

Resetting the ifstream with clear did the trick. Whoever maintains the 
NTC (/me looks at Dave Beckett)  might want to add the two lines to the 
code to fix this.

The two extra lines are preceeded with silly comments.

    model m1, m2;

    ifstream i;

    i.open(argv[ofs]);
    m1.read(i);
    i.close();

    //reset the stream so that we may read the second model without 
confusing poor kingtiny.
    i.clear();
    if (NOISY) {
        cout << "First model read:" << endl;
        m1.write(cout);
    }

    i.open(argv[ofs+1]);
    m2.read(i);
    i.close();
    //reset the stream... Well not really required here because we wont 
be reading from it again. But still.
    i.clear();
    if (NOISY) {
        cout << "Second model read:" << endl;
        m2.write(cout);
    }

Cheers,
