Add Notes to the timeline view

[rahul1]

Currently, we have a few react components for displaying timeline views:

• Timeline (generic)
• PatientTimeline
• ResourceTimeline
• EncounterTimeline
• ServiceRequestTimeline
• DefaultResourceTimeline

Most of these components do some kind of search for resources related to the root resource, and then display them in chronological order. For instance, many search for Communication resources that are linked to the root resource, which are treated as "comments".

However, many resources also contain a note field on them, that could also be interpreted as "comments". Some examples:

• Observation
• ServiceRequest
• MediationRequest
• ...

The request for this issue is to modify the appropriate timeline components to:

1. Check if the root resource has a note element
2. If so, add it to the timeline

Discussed offline, the complexity to support this did not seem worth the benefit.
