Process for downloading csv result summaries

[Lycanic]

I'm working on a branch #984 . This is somewhat related to #420 .

The intention is to allow the collation of data for non-VLE-run exams in a cleaner way than a current process (where a teacher may for example ask students to download their results as a pdf and then have to manually type this out).

At the moment, there is a button on the results page to download a csv file summarising the attempt, this can be encrypted with a password given by the author. In the exam package there is a page for collecting and analysing these files. As it stands, the page allows the upload of files and download of decrypted versions of those files.

I am now working on the display of data within the page itself and collation of student's results into one easy-to-use csv.

To do:

• [x] Collate student data
• [x] Read encryption/decryption password from exam definition
• [x] For each level of detail, download a csv corresponding to displayed data
• [ ] Tidy headers
• [x] Deal with random question orders
• [ ] Make it look nice
• [ ] Clear instructions (beginning from 'get students to download their data and send it to you')
• [ ] (Stretch) If the data the student downloads contained the full SCORM data model, then allow reviewing an attempt

Levels of detail

• [x] Student name - total score
• [x] Student name and score for each question
• [x] Full collated results for every student (headers, row for each student)
• [ ] (Stretch) Full attempt timeline

Details from today: Don't show/hide individual columns, have pre-set levels of detail Exam details are found with: await (await fetch("source.exam")).text()
