class_docstr: A CritiqueClient that creates tasks for workers on Surge AI.
  
  Surge AI concepts:
  
  - A **project** contains **instructions** and **questions**, which are templates that can contain
    placeholders.
  - A **task** is created in a project and contains **fields** that are interpolated into the
    placeholders in the project's instructions and questions templates to instantiate the actual instructions
    and questions in the task.
  - A **task response** is a response to a task by a single worker and contains answers to all the questions
    in the task.
  
  Mapping of HELM concepts to Surge AI concepts:
  
  - A `CritiqueTaskTemplate` maps to a **project**.
  - A `CritiqueQuestionTemplate` maps to a **question** template in a project.
  - A `CritiqueRequest` maps to a **task**
      - `CritiqueRequest.template` indicates which **project** the task should be created in.
      - `CritiqueRequest.fields` provides the fields that are interpolated into the placeholders in the
        projects' instructions and questions templates.
  - A `CritiqueResponse` maps to a **task response**.
  - A `CritiqueRequestResult` maps to a list of **task responses** across multiple workers for a task.

          CritiqueResponse(
              id=task_response.id,
              respondent_id=task_response.worker_id,
              answers={
                  question.name: task_response.data[question.name]
                  for question in questions
              },
          )
          for task_response in task.responses
