Removed the Auto Layout uiBox plan now that it's implemented. The Swift program will stay for now as I will mock uiGrid on it too.

-The visual layout has to be
-
-	H:|[edit0]|
-	H:|[button0(>=0)][button1(==button0)]|

-The problem now is that an empty box has to be represented by something. In the above hand-made example (which I have to test; TODO) we worked around the spaces. How do we do the same in code?
-
-The lower part of the box above is itself a single box laid out like so
-
-	hbox0:	[stretchy vbox0][area0]
-	vbox0:	[stretchy xbox0][hbox2][stretchy xbox1]
-	hbox2:	[stretchy xbox2][button7][stretchy xbox3]
-	xbox*:	[empty box]
-
-Do we need to start representing empty boxes using NSViews?
