1. Explicitly added OAuth2 and Session as the authentication types
allowed. Django Rest Framework allows the use of defaults via
settings, but this may have unwanted side-effects since there are
others using DRF with different APIs that have different requirements.

2. Created a ReadRestrictedDjangoModelPermissions class that is a
subclass of DjangoModelPermissions. DjangoModelPermissions only cares
about edit/update/delete permissions and makes everything world
readable by default, which is not desirable for this API.

3. Added the DRF login URLs for running this project locally.

4. Add edX fork of django-oauth2-provider to requirements.

Changed name of model CourseVideos -> CourseVideo.

Django model names should be singular.

URL change: /video -> /videos, added /admin

Changed the resource URLs to be plural for consistency with other
services in edx-platform. Added /admin for standalone running with
"manage.py runserver". Instead of using edxval.urls directly,
runserver now uses a top level urls.py that includes edxval.urls
as well as the debug toolbar and admin.

Switch to using migrations.

Using an older version of migrations to match edx-platform.

Support youtube encoded videos by using a different Profile.

Version conflict with another edx-platform dependency.

Use the correct course_id regex.

Expose course_id to the API

Rest Framework 2.4 requires request for serializers.HyperlinkedModelSerializer

Add authentication and model permission checking to REST API.

added note for profile_name convention

Added subtitle model and API

added create_video/profile to api.py for populating database

create_video and create_profile  will be used to populate database
for internal (not via HTTP requests) use.

Other notes:
-profile_name now has regex validator
-ddt==0.8.0
-100 percent coverage

added setup.py

Added setup.py and manifest.ini, adjusted requirements, and
removed admin.

Other notes:
-djangorestframework>=2.5.14

added pylint

Added pylintrc and pylinted the current code.

Other notes:
-added pylint==1.3.0

tests for PUT functionality

Assigned profile_name to be the identifier for EncodedVideos.
Tests for PUT have been added to check for expected behavior.
Attempting to PUT multiple EncodedVideos with the same profile
will return an error.

Other notes:
-url now accepts dashes
-reduced number of unique constants
-updated api.py tests with HTTP requests
-removed unused repr

POST for single EncodedVideo

POST for EncodedVideo implemented. Can now upload a single Video
with multiple EncodedVideos with profile_name as it's profile.
Cannot do any bulk operations. Serializers have been simplified.
Views are now using genericviews. Queries are now being tracked
in a few tests.

Other notes:
-Added django-debug-toolbar==1.2.1
-constants.py has been reorganized
-api.get_video_info uses new serializer

EncodedVideo part of the upload. Complete EncodedVideo dicts may
now be uploaded. Rejects all EncodedVideos of a Video when there is
an invalid EncodedVideo. Does not reject other Video when a differet
Video is invalid. Currently, EncodedVideo cannot be updated, they can
only be created.

Other notes:
-Added django-debug-toolbar==1.2.1
-constants.py has been reorganized
