Summary: Smart walking

Initial Comment:
It should be possible for DDD to display
arbitarily-complex data
structures by walking them.

I envisage the user operates the feature like this:
He displays a structure / object in the normal way.
He right-clicks on it and selects the (new) menu-entry
"smart-walk".
This opens a dialog window listing each pointer member
of the
structure/class.  The user can select which members to
walk,
and provide a maximum depth for each one.

When OK is clicked, ddd proceeds to expand the
list/tree/whatever as
far as possible, displaying each new object, stopping
only when:
(a) a pointer refers to an object already displayed, or
(b) the maximum depth for that pointer member is
reached, or
(c) a NULL pointer is encountered.

Thus it should be possible to expand trees or lists of
hundreds of 
objects automatically (with as few mouse-clicks as
possible).  Presently
this kind of expansion has to be done by hand.
