    Added some extra functions for use with FFTs · 976eac7b

    fft-frequency-vector can be used to make a vector that contains the actual
    sample frequencies (so you don't have to guess or write your own).
    fft-shift and fft-inverse-shift shift the zero frequency to the center (for
    easy plotting), and the inverse (for proper inverse FFT).
    These functions are comparable to fftfreq, fftshift and ifftshift in numpy (if
    anyone cares...).
