Should be fixed for 1.2.1 release

The most common normalizations seem to be Leahy, Miyamoto and Schlittgen.

The "default" apodisation does not appear to be a standard one (at least to me). Here is the code:

for (i = 0; i < len; i++) {
  _w[i] = (1 - cos(2*M_PI*double(i)/double(len)));
  sW += _w[i] * _w[i];
}
sW = sqrt(sW/double(len));
for (i = 0; i < len; i++) {
  _w[i] /= sW;
}

The LFI team has requested support for the following:

Amplitude and power spectra: In units of amplitude (Volt), power (Volt^2), amplitude spectral density (Volt/rtHz) and power spectral density (Volt^2/rtHz).

Proposal:

Add a combobox to the fftoptionswidget.ui so that the user can select between four options:

Power spectrum
Amplitude spectrum
Power spectral density
Amplitude spectral density

The default behaviour would be to produce the current output, and the setting would be "sticky" so the user can consistently produce the sampe type without the necessity of changing settings every time.

Additional change for PSD units

Created attachment 16293 [details]
Additional patch

In general looks good, and it restores the window creation into the psd 
generator where it belongs.  Only thing I can see is that the function type 
should use an enum, not a magic number.

SVN commit 546291 by staikos:

Apply Andrew's PSD patches so that I can continue work on PSDs without affecting
them.  Please add testcases and switch the function magic number to an enum
before closing the report.
