#register_template_handler(extension, klass) ⇒ Object

Register a class that knows how to handle template files with the given extension. This can be used to implement new template types. The constructor for the class must take the ActiveView::Base instance as a parameter, and the class must implement a render method that takes the contents of the template to render as well as the Hash of local assigns available to the template. The render method ought to return the rendered template as a string.
