Create functionality for saving the assessment

[sylvihuynh]

When the assessment of a task is done, the correction should be saved in a database.

We're thinking to save is as a json object to local storage or session storage.

It will probably be saved in assessment page when the user clicks "next" and loads in a new batch of answers.

Need to save

• answerId (our creation. It is _ )
• points
• candidateId
• questionId (maybe??)

Think about how you want to extract the information later. E.g. how easy will it be to get the data on Approval page and Completion page.
