expanded_numpy: Created the function enumerate_masks to simplify the process of converting masks stacks into labeled stacks. The conversion to label image is left up to the developer's discretion.
neuron_volumina_viewer: Created a mechanism that provides an operator for max projection onto a source. Added MaxProjectionConstantSource and MaxProjectionConstantRequest for dealing with determing the max projection of a constant source (will not change or become dirty) along one dimension.
