README

Continuous wavelet transform module for Python. Includes a collection
of routines for wavelet transform and statistical analysis via FFT
algorithm. This module references to the numpy, scipy and pylab Python
packages.

Now are inclued the wavelet cross-spectrun 
wavelet

The sample script (sample.py) illustrates the use of the wavelet and
inverse wavelet transforms and the results are plotted in a figure
similar to the sample_nino3.png image file.
