Boilerplate stats Branch

The official course boilerplate contains a branch including the Stats panel if you need.

You can clone the boilerplate into a new folder somewhere and checkout the stats branch.

git clone https://github.com/Sean-Bradley/Three.js-TypeScript-Boilerplate.git
cd Three.js-TypeScript-Boilerplate
git checkout stats
npm install
npm run dev
