% ECROBOTNXTSETUP
%   This function is used to retrieve and confirm necessity settings to build 
%   Embedded Coder Robot NXT generated code.
%   User can execute this function either with GUI or programmatically.
%
%   <How to use>
%   - GUI based set up (Dialogs pop up to specify necessity information)
%   ecrobotnxtsetup
%
%   - MATLAB prompt based set up (specify necessity information as arguments)
