For the distorted rotating black hole case I thought I had the runs 
completed. However, when I took a look at the waveforms, I saw only 2nd 
order convergence (very nice 2nd order convergence, though). I had 
unfortunately not noticed that the default values for WeylScal4::fd_order 
and Multipole::integration_method resulted in only 2nd order accurate wave 
extraction. I'm currently rerunning with modified parameter settings.

Is there any reason why the default values for those parameters could not 
be set to give higher accuracy?
