Unit testing framework?

[bendudson]

Is it worth looking at using a unit testing framework such as Google Test, in addition to physics example tests?

Also, need to automate the current tests so they can be run regularly

Basic test system now available, using Python scripts to automate running and checking output. For proper unit testing, the individual components need to be made more independent. Each component (e.g. Mesh) would then have a dummy implementation which could be used for testing other components.
