* Add fuzzy-adapter class to pick out subset data from FFT data server, instead
  of having separate methods in data server class.  Update spectrogram to use it.

* Give spectrogram layer one fft adapter per view, in case the views need
  different zero-padding levels.

* Reduce ridiculous memory consumption of MatrixFile for tall matrices.

  Still very much work in progress here.
