Parameterised ValueSets

Ontoserver now supports parameterised ValueSets as described in the FHIR Tools IG.

A parameterised ValueSet declares parameters in its definition and has their values supplied at expansion time. This lets a single ValueSet definition serve a family of related expansions — for example, “all descendants of X” where X is provided by the caller — rather than authoring and maintaining a separate ValueSet for each variant.

Parameterised ValueSet support is disabled by default; enable it with:

ontoserver.feature.parameterisedValueSets=true

Related to this, ValueSet search by url now also matches implicit ValueSets.
