function number_sf_chart(sys,option)

% Number the states from Stateflow in a Simulink system
%
% Syntax:
%   "number_sf_chart(sys,option)"
%
% Description:
%   "number_sf_chart(sys,option)" numbers the states of any or all
%   Stateflow charts in the Simulink system "sys".  If "option" is set to
%   "'allcharts'" then "number_sf_chart(sys,option)" numbers all
%   Stateflow charts in "sys".  If "option" is set to "'currentchart'"
%   then "number_sf_chart(sys,option)" numbers only the current Stateflow
%   chart.
