double t_dynamics::convergence_error

convergence_error and discretization_error give estimates of convergence: :: convergence_error -- change between the last iterations; :: discretization_error -- error in the upstream interpolation. When (and if) discretization_error >> convergence_error, the interpolation length should be decreased.

They should both be based on the same norm of the models, but what norm may be experimented with -- at present, it's H+/Htot just weighted by cell number, which makes the estimates sensitive to the structure of the primary ionization front.
