Bahmni - OpenMRS Ref Apps Interoperability

There are some variations (from the OpenMRS conventions) in the way Bahmni stores data.

• Ruled out diagnosis (stored as observations, and not as diagnosis, as agreed with OpenMRS community). One variation is we force clinicians to create 'presumed' diagnosis if they want to rule-out a diagnosis.
• 'Ruled Out' is stored as a 'Diagnosis Status' within the diagnosis obs group.
• We also need to store the first diagnosis for that concept. Initial Diagnosis Observation Id goes as an observation in the observation group for later diagnosis.
