Add endpoints to API

[courtneycb]

Adds the following API endpoints:

Endpoint for: Study class
URL: codewof.co.nz/api-studies
Accessible to: Admins
Data: Shows all studies with the following data for each: study ID, title, user types and researchers.

Endpoint for: StudyGroup class
URL: Not accessible through the browsable API. Used as a helper class.
Accessible to: Admins
Data: Shows all studies with the following data for each: study group ID, title and questions.

Endpoint for: User class
URL: codewof.co.nz/api-users
Accessible to: Admins
Data: Shows all users with the following data for each: user ID, email, first name, last name and user type.

Endpoint for: Profile class
URL: Not accessible through the browsable API. Used as a helper class.
Accessible to: Admins
Data: Shows all profiles with the following data for each: user ID and email.

Endpoint for: Attempt class
URL: codewof.co.nz/api-attempts
Accessible to: Admins
Data: Shows all attempts with the following data for each: attempt ID, datetime, question ID, user code for the attempt, if the tests passed or not and the profile of the user that submitted the attempt; this contains the ID of the user and email of the user.

The following URL takes a long time to load because of the data we are fetching. We aren't worried about this at the moment.
Endpoint for: Study class (except only shows one particular study)
URL: codewof.co.nz/api-study/?study_id=<study_id> where <study_id> is an integer (Primary Key of the Study)
Accessible to: Researchers of the study
Data: Shows all studies with the following data for each: study ID, title, user types and researchers. Will also show the study groups in the study; which is a dictionary containing the study group ID, title and questions in each study group (which is a dictionary containing the info for each question along with the info of attempts for each question). That's a huge mouthful so have a screenshot 😛 :

Also generate fake data for Attempts when we run ./dev sampledata. This currently only generates a max of 1 attempt per question.

Note that for testing the 'researcher' for every study is the admin account.

TODO:

• Allow all data for a particular study to be viewed at a single URL and......

• only allow the researchers of this study to access this.

• Adding researcher restriction currently duplicates queries - need to investigate if we can get away without doing this.

• Try and remove 'profile' from attempt information, or make profile be a dictionary of user ID and email so we don't have duplicate info.

• GET dropdown not working

• Customise theme? 😛

On all the pages when I select json from the drop down menu all the data loads fine, but the styling doesn't work. It's happening on firefox and chrome, no console error coming up on chrome though.
It doesn't affect the functionality though so maybe not a big issue?

This is supposed to be like this :)
