If I have an unevenly spaced complex dataset (its generated by an adaptive ODE 
solver), can I use it with the FFT transforms, OR do I need to apply an 
interpolation method in order to retrieve evenly spaced points first. The 
documentation examples don't make this clear. Next question is how do I re-pack 
the array to allow the FFT algorithm to work.
