Description

If the CDASegmentAnnotator encounters an empty segment, it throws away everything after that in the document. You can see this in the test document provided for TestCDASegmentAnnotator. The heading "CURRENT HEALTH STATUS" is followed immediately by the heading "Medications"; the test case misses the "Medications" heading, and "FAMILY HISTORY" after that. The sorted_segments loop is only incrementing the index variable for non-empty segments.

Patch attached.
