[patch][cla] BorderContainer collapsible feature

[peller]

Not sure what to call this exactly -- please make suggestions here -- but I think we need an option on the edge panes to have a little icon, sort of like an AccordionPane?, to collapse/expand the pane in the layout. Shouldn't be too hard to do.

(In [12404]) experimental expandopane in dojox - refs #5689 test has working bordercontainer with three children (two expando's and a tab in the center). left expando has three tabs (bottom aligned) and center tab has accordionContainer. right expando has AccordionContainer? as child.

[CLA] [PATCH] Adds (partial) support for vertical orientation expand/collapse.

[sfoster]

expandoPane_20080219.patch goes some way towards supporting expand/collapse in vertical as well as horizontal orientation for the dojox.layout.ExpandoPane?. Sorry, didnt get to tests and css but I wanted to put this back on the stack for the next person.

[dante]

(In [12518]) refs #5689 - add top/bottom expando option based on sfoster's patch. adds new test, and other cleanups.

I'd like for this to be in dijit eventually, possibly a different architecture where the code is in BorderContainer? itself not in a separate widget.

What's the plan on this?

to be merged w/ genro's patch pending CLA reception. sent friday, allegedy. refs #6781

Let's do the integration of collapsability into dijit for 1.3; 1.2 is focusing on purely visual issues.

As I said above, I hadn't envisioned doing this as a separate widget (ie, requiring the user to use an ExpandoPane to wrap their "real" widget), but rather to have it built in to BorderContainer, although it's up for discussion.

In any case, need to make sure the borders show up correctly so should wait for Nikolai to finish the refactoring (#6437, #6438, #6768). (Note that nesting a TabContainer inside an ExpandoPane could exacerbate the border problem.)
