Tree view for constant dimensions

[GoogleCodeExporter]

Since we capture so incredibly many vm options, it would be incredibly helpful 
to be able to expand them a level at a time in the UI.

(Of course sorting them helps, but I still think this would be useful; there's 
just sooo many of those damn things.)

I have a CL floating around somewhere that does "filter as you type".  Would 
that be sufficient?

That depends on whether a tree widget is easy. :-)
If it is easy enough, I really see a lot of value in having all those vm 
options completely invisible until I decide I _want_ to expand them.

Oh, wait, I might have misunderstood.  Are you talking about the options that 
appear in the table or the options that appear as constants?

It's in the summary :-) I only mean the constant dimensions; there's screenfuls 
of the buggers.

OK, I think we're on the same page then. "Invisible until I decide I _want_ to 
expand them" threw me because they already are hidden by default.  IIUC, you 
want to not have to unhide them all at the same time.

Anyway, the tree view in one form or another is part of the plan to be able to 
view detail for an individual trial, so something similar for those dimensions 
seems perfectly reasonable to me.

In the meantime I think the filter is a much more immediate solution that'll 
help a lot of use cases, so I'll just do that too.
