Use #HAML within a #yeoman #AngularJS app.

README.md

1. Add "grunt-haml": "~0.5.0" (or latest version) to package.json "devDependencies"
2. $ npm install to add grunt-haml to project node_modules
3. Update Gruntfile.js using this gists Gruntfile.js as an example
4. Watch and compile HAML files
5. Livereload HAML files
6. Register HAML tasks
