New sheet implementation possibilities

[John Darrington]

Based on recent conversations, I am of the opinion that the listbox approach
(which I linked to earlier) is likely to be better in the long term than 
anything based on GtkTreeView

Accordingly I have hacked up a demo based on that code.  This shows how a
sheet can be created with an arbitrary number of rows and columns and in
constant time and space.

If you are interested, check it out at

The nice thing is, that it is O(1) in the number of rows and columns (assuming 
that 
the total rows/columns exceed the number of visible rows/columns).


The big question of course, is how much effort it will take to get it to a
state that it'll fit into pspp.


Comments and feedback welcome.
