Thanks everyone. Sorry about the silly error.

I did run into one more problem before I was able to get it working. The 
mesh generator I was using uses a different handedness of tetrahedra 
than libmesh was expecting. The result was that I was getting an error 
message saying that I had a negative Jacobian. It took me a little while 
to figure-out what the cause was. So, when documentation is written 
about the format, it might be nice to include that point.

Thanks again,
Brent
