Adjust representation of 'foreign law' and 'foreign regulation' to better support integration with other ontologies.

[fjmanion]

The ontology has a US perspective for obvious reasons, but there are a few places where this could be mitigated. For instance, instead of using classes like 'foreign law' and 'foreign regulation', you could use 'nonUS law' and 'nonUS regulation' and make these classes disjoint with 'US law' and 'US regulation'. This might help integrate this ontology down the road with other ontologies.
