FFTW "Wisdom" support removed?

just checked it, and indeed it works. Calculation starts very fast in spite 
of FFTW_PLAN_TYPE PATIENT (probably because all the planning was already 
found in the Wisdom file). This is even better - then it is possible to 
always leave the FFTW_PLAN_TYPE PATIENT parameter (or even "EXHAUSTIVE") 
switched on. Very nice. Thanks again.

On my machine (AMD Opteron 6380, four CPUs on one mainboard), the 
calculations with careful FFT planning are more than three times faster (!) 
than without this feature.

Best regards,
