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.
