Description
This change implements support for use of the equivalence operators (~/!~) with Coding-typed expressions.
Equivalence between Coding A and Coding B is where:
- A subsumes B, and;
- B subsumes A.
Equivalence testing will be powered by the terminology server. The closure operation will be provided with with all Codings that need to be compared, and a pair of Codings will be judged equivalent if there are subsumes relationships going both ways between the two.
The equivalence operator will not be supported for any type other than Coding at this stage.

Research direction
Start by locating the FHIRPath equivalence-operator handling for Coding-typed expressions and the terminology server's closure operation. Verify equivalence when subsumes relationships exist in both directions, and confirm that other types remain unsupported.
