Deployment

[HarshDutt17]

Add changes to workflow, so that every Pull Request can have a preview of the work done before merging.

I guess for this, we will need to make 2 branches, and 2 deployed applications.

1. A kind of dev branch, where we will accept everyones pull requests. This will get directly deployed, as per the current case.
   If we don't like anything,we can revert the commit.

2. A deploy branch, where admins/ leads will merge the code from dev branch to deploy branch.
   This will contain our final deployed app.

Any other new approach is appreciated....
