uiFlash: Direct attention to UI object by short flashing

A property, e.g. the BackgroundColor, of a graphic object is flashed twice to the new value and return to the original. E.g. this can be helpful to direct the user's attention to a specific UICONTROL in case of wrong input.

FigH = figure;
BtnH = uicontrol(FigH, 'String', 'Hello', 'Position', [20, 20, 60, 20]);
uiFlash(BtnH, 'BackgroundColor', [1, 0, 0])
uiFlash(BtnH, 'Position', [16, 16, 68, 28]);
uiFlash(FigH, 'Position', get(FigH, 'Position') + [0, 20, 0, 0]);
