QuML Editor Upgrade

UI Design: https://docs.google.com/presentation/d/19yWPgL4s8mbT--RB1unnpPFiGZR1alFZ-jaTCN9YD3A/edit?usp=sharing

Overview:

Sunbird team has updated the QuML editor definition, essentially meaning that the way the objects are stored have been changed.

This page captures the:

1. Old flow

2. New flow

3. Engineering delta

Old Flow:

A question paper collection is created on Diksha, followed by project creation on vidyadaan, where the question sourcing life cycle as shown below happens.

New Flow:

1. Instead of question collection, create a question category

2. Define sections (chapters) at question set level

3. Define instructions at question set level (This will be used as instruction in the question paper)

4. Define blueprint at the project level for a question set

5. Contribute to a question set

   1. Instead of contributing a question set in the question paper collection, contribute a single question in the question set

   2. Instead of tags being defined at question set, define the tags at the question level

6. Question review - Instead of question set review, now the review will happen at the question level

7. Progress against blueprint - Show the progress against blueprint widget for the question set

8. Print service - Instead of Question paper collection hierarchy, update the print service to work on new question set hierarchy.

Next steps:

1. Define engineering step by step plan for migration

2. Close discussions on the new changed frontend flow
