Modify the FEValuesViews classes so that they compute a bunch of things already at construction time. This should make them much faster when you use them to evaluate stuff. On the other hand, it makes construction much more expensive and so the previous approach of creating them on the fly every time someone wrote fe_values[velocities] doesn't work any more. Rather, create all possible views objects at construction time of the FEValues object and simply return a reference to one of them when a view is requested.
