test_nanshe_learner: Added a test for generate_neurons_io_handler from nanshe_learner. This partially addresses #118.
test_nanshe_learner: Added a test for generate_neurons_io_handler from nanshe_learner. This fixes #118.
test_nanshe_learner: Added a test for generate_neurons_a_block from nanshe_learner. This fixes #119.
test_nanshe_learner: Added a test for generate_neurons_blocks from nanshe_learner. This fixes #120.
test_nanshe_learner: Added a test for generate_neurons from nanshe_learner. This fixes #121.
advanced_image_processing: Renamed the function region_properties to region_properties_scikit_image to specify what library it is using. Added a new version of the function region_properties, which currently simply calls region_properties_scikit_image.
advanced_image_processing: Added the function region_properties_vigra to supply an interface to vigra that will format the results in the same way as region_properties_scikit_image.
advanced_image_processing: Changed region_properties to call region_properties_vigra instead of region_properties_scikit_image.
advanced_image_processing: Changed generate_local_maxima_vigra so that it will used vigra.analysis.extendedLocalMaxima3D if the data is 3D and will resort to vigra.analysis.extendedLocalMaxima if the data is 2D. If the dimensionality is neither, it will fail an assertion.
