A description of the changes proposed in the Pull Request

• Dear GSF team,
  In scope of this PR integration test is provided, aiming to verify the integration of SCI-E model and IF framework.
  One test case included, covering the main flow - correct output creation in the console.
  Note: in the attached document energy-gpu is mentioned as an input parameter, however it is unused in the model itself.
