Creating branch for NWChem parser.
Created data directory for NWChem.
First basic NWChem test - single-point Hartree-Fock. The output file is temporary, since it is for version 4.6 instead of 5.1, and with symmetry.
SP (Hartree-Fock and DFT) test files for NWChem5.1.
I've set the nwchem parser up for testing for single point calculations.
Merge branch 'master' into nwchem

Conflicts:
