ODE to Data Graph Shapes

Geometric shapes in the DataGraph Physlet can now be data listeners.  The above examples solves the differential equations for theta and omega for a pendulum and passes these values to two data graphs for display.  A data connection is used to convert the theta value from the ODE to x and y values. This generates the pendulum motion in the left hand display.  Two other data connections are used to plot the theta and omega values in the right hand display.
