/* This interface defines tools for filtering sequences 
  of multi-channel samples ({dnae_datum_t}s).
  
  In a raw sequence, there is one datum for each codon, and
  the densities are computed for that single codon (either +1 or -1).
  A filtered sequence is obtained by repeatedly smoothing a raw sequence
  with a Gaussian filter of appropriate width, and resampling
  it with a step that is a power of two (positive or negative). */
