Static asset manager that allows you to declare multiple asset folders that will be searched when resolving static assets in your app.  You can even tell the asset-manager to scan your node_modules for assets that should be included in your app.  This makes it easy to package up content and reuse it across projects. This library also provides the ability to precompile all of the static assets into their production form (e.g., aggregated, minified content with hashed filenames).  Less support is built in so you can have Less files live side by side with css files.
