    # Registers a rendering extention.
    #
    # Slim, Markdown, ERB and SASS are registered by default.
    #
    # extention:: a Symbol or String representing the extention of the file to be rendered. i.e. 'slim', 'md', 'erb', etc'
    # handler :: a Proc or other object that answers to call(filename, context, &block) and returnes the rendered string.
    #            The block accepted by the handler is for chaining rendered actions (allowing for `yield` within templates)
    #            and the context is the object within which the rendering should be performed (if `binding` handling is
    #            supported by the engine). `filename` might not point to an existing or valid file.
    #
    # If a block is passed to the `register_hook` method with no handler defined, it will act as the handler.
    def register(extention, handler = nil, &block)
      handler ||= block
      raise 'Handler or block required.' unless handler
