Print wavelet transform intermediate results. The wavelet transform calculates a set of averages and coefficients (differences). These are calculated recursively. For example, for a time series with size 32, the first iteration of the recursive wavelet transform will calculate a set of 16 averages and 16 coefficients (differences). The next set of differences and avarages will be calculated at the start of the array (0..15) and will consist of 8 averages and 8 differences.
