fhir_mapping 0.13.0

FHIR Mapping Language parser and StructureMap transform engine for every FHIR version, over the fhir_node reflection contract and a per-version builder model.

0.13.0

• First release. The parser (StructureMapParser), the engine (FhirMapEngine, fhirMappingEngine), MappingVariables, the definition resolver and the FHIRPath host services, moved out of fhir_r4_mapping / fhir_r5_mapping / fhir_r6_mapping, which become bindings over it.
• FhirNodeBuilder: the mutable node contract the engine writes through; MappingModel<R>: what a version supplies (builders, fhir_path binding, version spellings).
• Maps and ConceptMaps are read by element name (MapView, GroupView, RuleView, ConceptMapView …); per-node caches are keyed by node identity (the typed engine stored them in builder user data whose setter returned a copy, so nothing was ever cached).
• Parser, per the Java reference: the old-format header's comment block is the map's description; /// experimental is read; a bare /// status = draft is accepted (published maps write it unquoted); quoted rule names keep their hyphens in R4B and lose them in R5 and R6 (fixName).
• Engine: translate over a CodeableConcept source looks the codings up one by one (a list fell through to "No translation found").
• Tests run over a JSON stub model: the 58 published example maps round-trip to their JSON, and every transform is exercised.
