#   DESCRIPTION:  ONLY USABLE FOR DIGIPOLIS EMPLOYEES!
#                 This script automatically pulls in the latest origin/develop into your local development branch,
#                 updates the version number based on the --type parameter and merges the development branch in the
#                 master branch before tagging and pushing to git. Jenkins does the rest.
