A Grunt plugin to iterate over every html file in a Django project and compress javascripts and stylesheets.

/*
 * Get HTML files function

 * An useful utility to iterate over every folder in any path and return an
 * array containing all HTML files inside.
 *
 * You can exclude folders by name by passing it as an excluded dirs array
