advanced_numpy: Added a series of generally useful functions that build on NumPy to add simplicity in providing views and performing operations on arrays with mismatched shapes and so on.
advanced_iterators: Added the cumulative_generator for performing operations on more and more elements of a list. Was useful for advanced_numpy initially, but is no longer used.
wavelet_transform: Changed Error to Exception.
advanced_image_processing: Various improvements. Broke out preprocess_data and parameterized it. Added many steps to wavelet_denoising. Still more debugging to be done in wavelet_denoising. Also, preprocess_data needs more steps added.
simple_image_processing: Added a comment.
batch_learner: Now used serializers for reading and writing NumPy structured arrays.
