[Bug-apl] ⎕FFT

[Juergen Sauermann]

Hi,

for those of you that are interested in signal processing and the like, I have added
⎕FFT which computes discrete Fourier transforms. ⎕FFT uses libfftw3, which needs
to be installed before GNU APL is being ./configure'd.

I also added a workspace gnuplot.apl which allows you to visualize some ⎕FFT results
with the gnuplot program.

Enjoy,
/// Jürgen
