Generating careplan using workflow library.

[parthfloyd]

Describe the bug
When trying to generate a careplan using the generateCarePlan method from FhirOperator.kt, it fails with an Notimplemented error.

Component
Workflow library

To Reproduce
Steps to reproduce the behavior:

1. Creating the patient, plandefinition and encounter resource in fhir engine. (Used dummy data from the test files)
2. Using the generateCarePlan method with the respective id of the resources saved.

Expected behavior
To return the careplan object.

Additional context

• I tried running it on the demo application, on the master branch.
• The patient, plandefinition & encounter resources - patient-plandef-encounter.txt.
• Stack Trace:

I tried out the generateCarePlan method again after the FhirEngineDal.read method was implemented.
It failed with a different NotImplementedError, in the PlanDefinitionProcessor.java of CQL-Evaluator.

Precisely, URI Definition & Questionnaire Definition Evaluation is not yet implemented in the resolveDefinition method of PlanDefinitionProcessor. For now the method only supports "PlanDefinition" & "ActivityDefinition".

The Plan Definitions I tested with:

1. Child Routine Visit Plan Definition
2. Plan Definiton Emcare

The Error Stack Trace Respectively:

1. stack-trace-uri-definition-evaluation.txt
2. stack-trace-questionnaire-definition-evaluation.txt

The Patient & Encounter resource: patient-encounter-resource.txt

1. PlanDefinitionProcessor.java Github reference
2. CQL Evaluator Github
