docs: Load a template from the DOM, by default. Override this method to provide your own template retrieval For asynchronous loading with AMD/RequireJS, consider using a template-loader plugin as described here: https://github.com/marionettejs/backbone.marionette/wiki/Using-marionette-with-requirejs
