-- So we have two problems with serialization.

-- ONE: The objects.collection looks like this:

{
  1 = {
    x = 30,
    y = 50,
    type = {
      -- this is a reference to objects.node or objects.arc or whatever, a 
      -- table containing its OWN information that we don't want to duplicate
    },
  },
  -- etc.
}

-- Which means we need to have a transform on object instance's type when saving and loading.
--
-- That's not too scary. This next one is a bit tougher, though.


-- TWO: An arc looks like this:
{
  segments = 4,
  head = { },
  tail = { },
  -- where both head and tail are references to node instances, stored 
  -- elsewhere in the objects.collection.
}

-- So now we have to either keep track of things that have been already 
-- serialized (difficult since lua does not appear to expose any kind of hash 
-- for tables or references) or transform the head and tail into the correct 
-- index in objects.collection at save, and back again on load.
--
-- Ideas?
