function appDataStruct = wizard(appDataStruct, callbackStruct, wizardName)
%WIZARD Obsolete function
%   WIZARD is obsolete.  It will be removed in a future release.

% Template for building GUI wizards.
%
% INPUTS: appDataStruct: can be empty or have fields chock full of nuts
%         callbackStruct: requires these fields with valid function pointers.
%                         doCancel      - call on cancel press and window close
%                         doBack        - call on back press
%                         doNext        - call on next press
%                         doFinish      - call on finish press
%                         doKeyPress    - call on key press over window
%                         doPanelChange - call on card panel change
%
% OUTPUTS: appDataStruct: any fields passed in get passed out.  These fields get set.
