  FT_PREPROC_POLYREMOVAL removed an Nth order polynomal from the data
 
  Use as
    dat = ft_preproc_polyremoval(dat, order, begsample, endsample)
  where
    dat        data matrix (Nchans X Ntime)
    order      the order of the polynomial
    begsample  index of the begin sample for the estimate of the polynomial
    endsample  index of the end sample for the estimate of the polynomial
 
  If begsample and endsample are not specified, it will use the whole
  window to estimate the polynomial.
 
  For example
    ft_preproc_polyremoval(dat, 0)
  removes the mean value from each channel and
    ft_preproc_polyremoval(dat, 1)
  removes the mean and the linear trend.
