Create rule DDF00016: studyEpochName should have a one-to-one relationship with studyEpochDescription

[ASL-rmarshall]

Create rule defined for #18

[ASL-rmarshall]

Same logic as DDF00001 (#23)

[ASL-rmarshall]

Although the logic for this rule is exactly the same as that for DDF00001, I have created this as a separate rule because we haven't yet decided if DDF00001 should be a generic rule (see discussion in #3).

Negative and positive tests returned message "absent variable skips"
"errors":[1 item 0:{2 items "error":"Column not found in data" "message":"isEnabled, isRequired"

[DianeWold]

Apparently ran the test data against the wrong rule. Reran tests. Negative data gave 5 negatives, as expected. Positive data successful.

[ASL-rmarshall]

This rule has been updated to only report where rel_type = "definition". Associated test data have been updated and unit tests have been rerun successfully.

Rule deleted in DDF Phase 4. Saving a copy of definition:
