This adds a bunch of methods for applying functions to rolling windows on
NDListdata. That introduced a new type,RollingResult.This also introduces methods for Fourier analysis: FFTs for
NDlist<double>as well as a.spectrogramextension method that takes FFT on a rolling window.Tests have been added for new stuff, but more complete testing would be nice to add later.
