added rating component (and small process details page) #86

[AlexanderLichtenegger]

resolves #86 Added:

• Process Rating Component and Module
  • The component shows existing process ratings and allows users to add new ratings
  • A rating consists of the rating itself (stars) and a comment
  • The component is used like this: <ngx-process-ratings [processId]="processId"></ngx-process-ratings>
  • The component fetches and posts the ratings itself
• Store Process Details Page
  • Added a Store Process Details Page where the Rating Component is used
  • More content will be added to it in another task

Notes:

• Also import the store processes from the attached file in the "ippr_store" database. processstore_testdata.sql.txt
• The implementation in the backend has to be done. To show some example ratings: Set "testMode" to true in "process-ratings.component.ts".

Review

• Looks very good and I agree with the implementation
• Component does exactly what it should do and is nicely implemented
  • Although this does not include a code review as we have no time for code reviews and other components and code would also need huge refactoring.
• JSON for a rating/comment looks fine and can be used like this in the backend.

ToDo

• As soon as the backend provides the necessary endpoints, reuse this branch and link the functionality to the backend to actually store all comments
• Only users who are in an organization that has already bought a specific process should be able to comment or make a review.
