title: User authentication using django-oauth-toolkit
body: <p>I am new to OAuth and Django Rest Framework. I have created a user model in django, now I want to use it on my native mobile application. So, how do i create authentication using OAuth. What flow should I use? Do i need to create a client application for every user? 
  Please help me with it or provide a nice tutorial. I have read the documentation of django-oauth-toolkit. I have understood the basics, but did not understand the implementation.</p>
