Testing

Testing of NWChem 6.8 with both gcc and Arm compiler. The test script doqmtests.mpi has been used to test these builds on a TX2 system. Currently there are a number of failed tests (currently 44 from 240 tests) but mostly for very minor numerical differences compared to the provided test result.

The following test cases from doqmtests.mpi fail for very minor numerical differences and are deemed acceptable.
