function sigsetappdata(h, varargin)
%SIGSETAPPDATA Set the application data with multiple fields
%   SIGSETAPPDATA(H, NAME, VALUE) sets application-defined data for
%   the object with handle H.  The application-defined data,
%   which is created if it does not already exist, is
%   assigned a NAME and a VALUE.  VALUE may be anything.
%
%   SIGSETAPPDATA(H, NAME, SUBNAME1, SUBNAME2, etc, VALUE) sets the
%   application-defined data using multiple names to save the data.
