/* Compare sclang inbuilt fft with SignalBox rfft - refactor of tests by @spluta

What we're seeing is that sclang's complex fft is by far the fastest.

Relatedly, if a real fft (+freqs only) is desired, the quickest approach is to discard -freqs, and then use rfftToFft to create a mirrored spectrum for resynthesis via ifft.

It would be worth investigating refactoring the algorithms found in SignalBox, keeping in mind preserving the current interface(s).
