The concept is simple, and exactly matches the names,
*once you get it* ;-)
but as with so many things, getting it may not be
AHEM! (Tapping pointer on lectern) =====
"Inside" is transitive-- (could it be otherwise?)--
a b c d ...
so in this example, b is inside a, c iis inside b, d
is inside c, etc.
Now, the problem with only having that one dimension
to represent containment is that in this model,
each thing can only contain *one other* thing,
like nesting Russian dolls.
So to put more than one thing inside A, we need
some way of representing it, a contents list;
and a simple way to do that is have it dangle from
the first contained object. A design choice is
whether to have some title, or just the first item,
at the top of the list; I choose to put the first item,
since there might not even be a second.
The expected structures is:
d.contents \/ d.inside => ("|" here means "no connection)
where for some reason (probably visual convenience in
some context), A *might* be connected to B, abd c to d,
but those connections have no system-supported connection.
