lens problem: some small performance improvements

Browse Source 
the changes enable the storage cache and the intensive quantity cache
for all simulators of the lens problem and automatic differentiation
for the one which uses the ECFV discretization.

while the performance improvements are not worthwhile for the problem
in its default incarnation (using automatic diffentiation even
slightly degrades performance), it speeds up linearization by about
30% if the grid exhibits 16 times as many elements (e.g. by passing
the --grid-global-refinements=2) parameter.
