#
#  A lifting implementation of this biorthogonal wavelet filter bank
#  designed as a spline variant with less dissimilar lengths.  Original
#  filter-bank coefficients published by Cohen et al.; lifted implementation
#  described by Daubechies and Sweldens.  This biorothogonal wavelet has
#  seen widespread use (usually in filter-bank form) in
#  image-processing applications since it was used by Antonini, et al.
#
#  Permitted boundary methods:
#    symmetric extension, periodic extension, boundary wavelet
#
#  Permitted signal length:
#    any, start with even- or odd-indexed sample
