5.7 Object

This groups a few items which had no obvious home and which change the format of objects.

Duplicate

Copy an object, stripping off any derived classes. For images, this really takes a copy of the underlying object (using im_copy()).

List to Group

Changes lists (see Math / List) into Groups (see Edit / Group) and back. A list os an ordered collection of objects. A group is a list that nip2 will automatically iterate over.

Break Up Object

This tries to take an object apart. So a multi-band image becomes a list of 1-band images. A matrix becomes a list of vectors, and so on. Assemble Object is the inverse.
