/**
  This is an integer version of the wavelet packet tree base
  class.  This class can be used for both compression and
  time/frequency analysis of an integer time series.  However,
  this version was developed for lossless integer compression.
  
  This class may be subclassed for classes that apply the
  wavelet best basis algorithm or for time/frequency 
  wavelet packet trees.
