Use the CvodeIntegrator class to integrate any system of ordinary differential equations
using an adaptive algorithm that works on wellbehaved and stiff systems.
The system of differential equations is defined using a DifferentialFunction
delegate. This is a delegate that takes one real argument (the time value), and two vector arguments
(the current value and the current derivative). The last argument is passed by reference and must also
be returned.
To set up an integration, set the DifferentialFunction property equal to the object that
defines the system. Set the InitialTime and InitialValue properties to the initial
time value and function values, respectively.
To perform the actual integration, call the Integrate(Double) method with the desired final time.
This method returns the function value at the final time. You can call this method multiple times to get
function values at intermediate positions.
