==== Description: ====
Does a fast discrete wavelet decomposition on a file holding  a numerical
array whose length is an integer power of 2 and also does inverse
transformation. What makes this code unique is that it is lightweight and
written (in C) to behave like a unix tool. It works with pipes and redirects
and therefore can be piped with other unix tools such as sort or head, etc and
is ideal for calling from within Bash or other scripts. 

Many other wavelet software packages are large and cumbersome or are written
for proprietary applications such as Matlab or Mathematica. This project is
different from a project like FFTW3 because meant to be easy to use from the
command line like cat or grep.

Options are available to use several wavelet filters from the Daubechies and
Coiflet families of filters. New filters can be added in a relatively
straightforward way so the project is extensible without requiring steep
learning curve. 

This project would make a valuable addition to those interested in science,
math, and engineering.  Also, I am a physicist, not a professional programmer
so I am hoping to attract interest and hopefully improve the project.
