Question Generation flow

[stefanruseti]

1. add text
2. get possible answers - fixed number of types from backend (e.g. NER, Keyword, RL) + user defined
3. the user can select fragments of text and will be labeled as "user defined"
4. set parameters for question generation: number of questions per answer, number of answer choices
5. send question generation job to the processing queue
6. show a table with the generated questions on a separate page (link from the queue). Columns: Question (editable), Correct Answer, Candidate 1, .. Candidate n-1, Complexity, Feedback (with editable subcolumns: relevant, correct, coherent).
7. save final question set to the database
