Wavelet Analysis

New subroutines for computing, inverting, and displaying wavelet transforms have been added:

The WAVFT subroutine computes a specified wavelet transform of one-dimensional data.
The WAVGET subroutine returns requested information encapsulated in a wavelet transform.
The WAVIFT subroutine inverts a wavelet transform after applying specified thresholding to the detail coefficients.
The WAVPRINT subroutine displays requested information encapsulated in a wavelet transform.
The WAVTHRSH subroutine applies specified thresholding to the detail coefficients of a wavelet transform.
