gitfix.sh

# A handy utility for quickly forking and cloning and project
#
# Usage `gitfix <git-repo-link> [optional --no-install] [optional --no-fork]`
# 
# What it does
#   - forks the repository to the current user's GitHub renamed to <org-name>--<repo-name>
#   - performs a shallow clone of the repository (last commit from master only) into `~/gitfix/<org-name>--<repo-name>`
#   - the original repository will be the remote `origin`, the fork will be the remote `<github-username>`
#   - changes the working directory to be `~/gitfix/<org-name>--<repo-name>`
#   - runs `yarn` to install dependencies
#   - opens the project in WebStorm
