  FILTFILT overrides the filtfilt function for analysis objects.
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: FILTFILT overrides the filtfilt function for analysis objects.
               Applies the input digital IIR filter to the input analysis object
               forwards and backwards. If the input analysis object contains a
               time-series (tsdata) then the filter is applied using the normal
               recursion algorithm. The output analysis object contains a tsdata
               object.
 
               If the input analysis object contains a frequency-series (fsdata)
               then the response of the filter is computed and then multiplied
               with the input frequency series. The output analysis object
               contains a frequency series.
 
  CALL:        >> b = filtfilt(a,pl)
 
  INPUTS:      pl   - a parameter list
               a    - input analysis object
 
  OUTPUTS:
               b    - output analysis object containing the filtered data.
 
  PROCINFO:    The input filter object with the history values filled in are
               always stored with a plist in the 'procinfo' property of the AO.
               The key of the plist to get the filter is 'FILTER'.
