computes power spectral density of one or two files
<pre>
<in1> Input 1 file name
<out1> File to receive PSD of input 1
<nfft> Desired transform size. Any factor supported [DEF=1k]
<win> Name of time window to be computed and applied to the data [DEF=HANN]
<over> The fraction of <nfft> to overlap blocks [DEF=0]
<navg> Num of transforms to average in computing each output FFT frame [DEF=-1]
<in2> Input 2 file name [OPTIONAL]
<out2> File to receive PSD of <in2> [OPTIONAL]
<cross> File to receive PSD of <in1> * conjugate of <in2> [OPTIONAL]

This command performs Fast Fourier Transforms on a stream of data. It calls the
FFT primitive with default navg=-1 and default switches /1D/PSD.

To match X-Midas behavior add the /PARTIAL=NONE switch.
