/**@class TimeUnitBox
*A pair of buttons, arranged one above the other, labeled "+"/"-". These buttons
*are to be paired with the TimeSpinBox widget. Their function is to provide
*a way to cycle through the possible time steps using larger intervals than the up/down
*buttons of the TimeSpinBox. For example, say the Spinbox currently shows a timestep of
*"1 sec". Increasing the timestep with the spinbox up-button will change it to
*"2 sec", while using the "+" button of this widget will change it to "1 min".
*
*The idea is that these "outer" buttons always change to the next even unit of time.
*
*@note this widget is not to be used on its own; it is combined with the TimeSpinBox
*widget to form the TimeStepBox composite widget.
*@short provides a second set of up/down buttons for TimeStepBox.
