title: Creating users with quickblox - session token generation
body: <p>I want to make a web-page that creates users.
  To do that I have to generate a session token.
  I looked up in the Quickblox's documentation and I found nothing about it.</p>
  
  <p>Could anyone please guide me, step by step, how to generate a session token? (from signature-generation, to request, and finally obtaining the session token).</p>
  
  <p>I might have skipped a step, if so, feel free to correct me.</p>
