#
#  A lifting implementation of the biorthogonal spline wavelet filter bank.
#  Original filter-bank coefficients published by Cohen et al.;
#  lifted implementation described by Sweldens as linear lifting.
#  Swelden's linear-lifting scheme did not employ unitary scaling;
#  this implementation does in order to give output consistant with the
#  corresponding filter-bank implementation.
#
#  Permitted boundary methods:
#    symmetric extension, periodic extension, boundary wavelet
#
#  Permitted signal length:
#    any, start with even- or odd-indexed sample
