advanced_image_processing: Corrected return for wavelet transform.
denoising: Added functions to generate NumPy masks to extract noise or significant features.
denoising: Cleaned up doctests. Changed remove_noise to take output_array as an argument instead of in_place. This specifies an output_array location; however, if not specified it will create an array to use.
denoising: Added noise_estimate instead of passing parameters to estimate_noise. If noise_estimate is not specified, then it calls estimate_noise with default parameters. Also, removed function remove_noise as it is largely the same as using the mask with a simple multiplication.
advanced_image_processing: Contains all portions of ADINA. However, needs some tweaks before testing and profiling.
