Trying to get nvim easy to set up

Manual things that should probably be automated

• This repo needs to be cloned into ~/.config
• Neovim will have to be installed (brew install neovim)
• YCM will probably need its install script run
• Exuberant CTags will need to be installed
• might have to run sudo pip install --upgrade --force-reinstall neovim
  • Speaking of which, hopefully pip is installed on the machine.
• Not a good way to test some of this except with a fresh machine.
