Description
Will Power has identified a situation (periodic forcing) which seems to show that in that situation ANUGA demonstrates diffusive behaviour (first order in space). The problem seemed to be resolved when vertex limiting is turned off and second order timestepping is used. I claim that changing over to edge limiting should also provide a solution to the problem. Edge limiting should be implemented and tested for robustness.

It appears that the edge_limiter with appriate beta values works fine inasmuch as the auto validation tests pass. However, many unit tests need a compatibility flag or to be redono.
