Sliding Window Over Wave

// This aims at defining a window (or bin) that will slide along a waveform,
// perform FFT analysis and curve fitting and to retrieve fit values at each window position
// before moving on to the next position as defined by a given step-size and looping until
// all data-points are exhausted.
