A general framework for fast Fourier transforms (FFTs) in Julia.
Documentation:
This package is mainly not intended to be used directly.
Instead, developers of packages that implement FFTs (such as FFTW.jl or FastTransforms.jl)
extend the types/functions defined in AbstractFFTs.
This allows multiple FFT packages to co-exist with the same underlying fft(x) and plan_fft(x) interface.
To define a new FFT implementation in your own module, see defining a new implementation.
