function val = subsref(self, s)
% overloading subscripted reference for objects
% Dot Notation vs. Function Notation
%
% MATLAB classes support both function and dot notation syntax for calling methods. 
% For example, if write is a method of the class of object nc, then calling 
% write with function notation would be:
%
% nc = write(nc, 'mode');
%
% The equivalent method call using dot notation is:
%
% nc = nc.write('mode')
%
% However, in certain cases, the results for dot notation can differ with respect 
% to how MATLAB dispatching works:
%
%   If there is an overloaded subsref, it is invoked whenever using dot-notation. 
%   That is, the statement is first tested to see if it is subscripted assignment.
%
%   If there is no overloaded subsref, then setColor must be a method of X.
%   An ordinary function or a class constructor is never called using this notation.
