Ontology 2.0: Implement Referenced Criteria

[juliangruendner]

sq2cql should be extended to support referenced criteria.

These are defined as one criterion referencing another criterion which can include all the elements of a normal criterion except the attribute filter of type "reference". => Only one level of nesting should be supported, so that: A criterion can have an attribute filter of the type "reference" which is a criterion, but the referenced criterion cannot have an attribute filter of the type "reference".

Example: Specimen with diagnosis Assumption: Given the Structured Query (SQ) and mapping below.

Example Structured Query (SQ) with attributeFilter of type 'reference':
