Vytvorit endpoint (API) na ziskanie celkoveho hodnotenia predmetov

Ludia chcu do svojich aplikacii ziskat celkove hodnotenie predmetov. Aby si nemuseli stale updatovat databazu na najnovsie data, stacilo by im poskytnut api, ktore by vracalo vysledky.
Query:
```sql
select code,name,slug,season_id,score from Subject,AnswerSummary,Question where AnswerSummary.subject_id=Subject.id and AnswerSummary.question_id=Question.id and isSubjectEvaluation=1;
```
