It looks nice. At some point (soon), it would be good to have support
for plotting ODE solutions with Viper from DOLFIN. Currently, this is
difficult to do since the ODE solution produced by DOLFIN is not
stored other than to file. One of my students (Benjamin Kehlet) is
working on a new class ODESolution which will provide the necessary
data to do ODE plotting (and store/retrieve data for solving the dual
problem).
