Topic: CQL_Engine and ConceptRef Error

@Bryn Rhodes In attempt to do a retrieve as follows using a Concept to filter the results:
define "test" : [Condition : "Heart Failure" ] C
We got the error: evaluate not implemented for class ConceptRef. So we looked in the source code at:
https://github.com/DBCG/cql_engine/tree/master/cql-engine/src/main/java/org/opencds/cqf/cql/elm/execution
Indeed, no ConceptRefEvaluator.java file exists (though one for CodeRefEvaluator.java does). Is this a misssing file, if so we'll submit a pull request accordingly.

Yes, that's an element that is not implemented. Concepts are explicitly disallowed within eCQM program measures (by the CQL-Based HQMF IG), so we haven't spent time on that feature.
