Purpose of this function is to take a list with {TimeOfSample,Data} pairs and perform FFT to show spectral content.  It assumes the data is evenly spaced.

I know it's simple.  Any input welcome or extra features you think would be useful.

Input: {{TimeOfSample,Data},...} pairs
Output: {{Frequency, Energy},...};


I am considering looking at the averaging of the time between samples to detect sample time discontinuities by looking for a maximum deviation from max time difference to min time difference.

Any input welcome.
