Added support for the traffic endpoints found at https://developer.github.com/v3/repos/traffic/.
We added four functions to the Repository class (one for each of the endpoints) with corresponding unit tests.
Fixes#926
Wraps the parts of the notification API that allows the user to mark notifications as read.
New methods are :
- Notification.mark_as_read : marks a single notification thread as read
- Repository.mark_notifications_as_read : marks all the notifications for a given repository as read
- AuthenticatedUser.mark_notifications_as_read : marks all the notifications as read
Aims to fix : https://github.com/PyGithub/PyGithub/issues/571 and simply uses the APIs described on this page : https://developer.github.com/enterprise/11.10.340/v3/activity/notifications/
A weird thing I noticed doing this is that Repository.notifications_url doesn't seem to be usable directly. I used Repository.url + "/notifications" instead.

## What does this change do?
Adds a small example of how to get at the date a commit took place.
### Changes
#### doc/examples/Commit.rst
Adds a block of code that demonstrates how to get at a commit's date.
## Motivation
This example is in the spirit of #874.
When I began using PyGithub it was not readily apparent to me where the commit date was being abstracted to. Being unfamiliar with Git's API, it took some convincing for me to be satisfied that the `Commit.commit.author/committer.date` path would get me the commit date.
I would hope that this would save somebody a little bit of time in the future.
## How has this been tested?
I've built the docs locally and made sure the HTML is generated as expected.
