NBUTTONDLG: A Generic Implementation of QUESTBOXDLG

Generates an n-button question dialog box

An expansion over QUESTBOXDLG, which allows up to 3 button selections, NBUTTONDLG(Question, ButtonLabels) creates a modal dialog box that sizes to accomodate a generic number of buttons. The number of buttons is determined by the number of elements in buttonlabels, a 1xn cell array of strings. The name of the button that is pressed is returned as a string in userchoice. NBUTTONDLG will theoretically support an infinite number of buttons. The default parameters are optimized for 4 buttons.
NBUTTONDLG returns the label of the selected button as a character array. If the dialog window is closed without a valid selection the return value is empty.
NBUTTONDLG uses UIWAIT to suspend execution until the user responds.
Example:
UserChoice = nbuttondlg('What is your favorite color?', ...
{'Red', 'Green', 'Blue', 'Yellow'} ...
);
if ~isempty(UserChoice)
fprintf('Your favorite color is %s!\n', UserChoice);
else
fprintf('You have no favorite color :(\n')
end

The Question and ButtonLabel inputs can be followed by parameter/value pairs to specify additional properties of the dialog box. For example, NBUTTONDLG(Question, ButtonLabels, 'DialogTitle', 'This is a Title!') will create a dialog box with the specified Question and ButtonLabels and replace the default figure title with 'This is a Title!'
