* #NmtNewtButtonBox is a container for creating and holding
* #NmtNewtButtons.
*
* A button box can be either horizontally or vertically laid out, and
* has two sections within it: the "start" (left or top) and "end"
* (right or bottom). Buttons are added from left to right or top to bottom
* within each of the two sections.
