Installs LLVM's clang-extra tools for you because it's a pain otherwise.

Though not required, it is highly recommended you install Ninja prior to installing this package (it will automatically detect that you have ninja installed).

# the below command is not required, but _highly_ recommended
# (if it doesn't work, just install ninja manually)
(command -v brew && brew install ninja) || sudo apt-get install ninja-build

# get some coffee going...
npm i -g clang-extra

Performs a shallow clone of each repo's origin/master/HEAD ref so you're getting whatever latest version is there. Since some of these mysteriously don't work without libcxx being cloned/built alongside the extras, it has been included as well.

And no, running npm install clang-extra again won't update it. Thanks to NPM's infinite wisdom, the entire directory is cleared before it re-installs so it forces a rebuild of - you guessed it - all 2700+ files.

So just be careful when you try to re-install. The script has been built to update but the functionality is useless since NPM kills all of it anyway.
