/**

  The packdata_list class is based on a subclass built from a
  FIFO_LIST<packdata *> instance of the FIFO_LIST template.

  The packdata_list is constructed by traversing the wavelet packet
  tree depth first, left to right.  New elements are added to the end
  of the list, ordering the list from front to back.  The resulting
  list reflects the ordering of the wavelet packet tree nodes the make
  up the best basis.

  This class extends the FIFL_LIST instance by adding a print function.
