Changeset 4686 for anuga_core/source/anuga/shallow_water

Timestamp:

Message:

Tried tests and automated validation with non-optimised slope limiters and verified correctness bar three tests that gave slightly different results.
As the main validations passed, I added assertions in the unit tests to
pass using the old non-optimised limiters.

The slope limiters will be addressed in the future to make the code cleaner
and also look for better optimisation (including dry cell exclusion).
