Section 6.2: Data Output - Outcome: Drop cannot tell and add non-applicable

[maryjom]

From Alistair Garrison: Under 6.2 - I would remove "Cannot tell" (as it conflicts with writing automated tests - if you cannot tell re-write the test!) And, I would include "Non-applicable".

[WilcoFiers]

RESOLUTION: Add a note that cantTell results should be limited to semi-automated rules
