/*
    This script takes the current status of the develop branch
    and merges it automatically with the master branch. 
    It will ignore any modifications in the master branch.

    This will trigger a deployment of the master branch to
    the live server.

    Not everyone has the right to make changes to the master 
    branch. Which is why we're using a GitHub token for a 
    generic account.
