Solving ODEs backwards

When solving differential equations, it is often helpful to solve orbits both backwards and forwards in time. If you set Start Plotting to -10 and Stop Plotting to 10 on the Time panel of Numerics Editor, solutions first computed backwards from the initial conditions for 10 time units, and then forwards from the same initial conditions for another 10 units of time.
