Class: Care_event

Description of: Care_event

Class steward is Orders/Observation
A subclass of Service_event and a superclass that captures the data related to a kind of service that produces a change in the target of service and includes medication administration, surgeries, teaching, dressing changes, therapeutic listening, etc. This class is orthogonal to Assessment_event.

Rationale: Since some healthcare services produce changes in the target of service, these actions need to be captured and statused with their own set of attributes.
