Add install script

[Cyberbeni]

Here is the terminal part from my personal mac install script:

REAL_PATH="$(readlink "${BASH_SOURCE}")"
cd -P "$(dirname "${REAL_PATH}")"

link_to() {
  if [ ! -e "$2" ]; then
		if [ ! -e "$1" ]; then
			printf "\nWARNING: cannot link $1 because it does not exist\n"
		else
			sudo ln -s "$1" "$2"
			printf "\nLinked $2"
		fi
  fi
}
link_dotfile() {
  link_to $(pwd)/$1 ~/.$1
}

link_to $(pwd)/com.googlecode.iterm2.plist ~/Library/Preferences/com.googlecode.iterm2.plist

if ! command -v brew > /dev/null 2>&1; then
  printf "\n### Installing Brew\n"
  ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  brew analytics off
fi

brew install zsh
if ! [ $(ls /Applications/iTerm.app 2>/dev/null) ]; then
  brew cask reinstall iterm2

  sh -c "env() {
    echo 'Dont want to stop installing by changing the environment to zsh'
  }
  $(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
  rm ~/.zshrc
  link_dotfile zshrc


  git clone https://github.com/powerline/fonts.git --depth=1
  cd fonts
  ./install.sh
  cd ..
  rm -rf fonts
fi

If I remember correctly, the only change in the iterm plist is the color and font.
