Created Auto Documentation for Backend using flask-selfdoc

[amlannandy]

Description

Created auto-documentation for the server using self-doc.
One can view the documentation by going to the root route of the server. i.e localhost:5000/
Now, whenever a new route is created. We just have to add the self-doc decorator to it and it'll be shown in the documentation. We can also add a description to the route by using doc strings for that route's function.
