Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(*a, &b) ⇒ Object

Re-defined render

The method_missing method is great but it ties the system too much to markaby. It makes also harder to debunk wrong methods since the call- stack is longer. Finally, it encourages to put the view in the controller, which is considered bad in MVC style (that’s what ppl say)

Render is a method that gets the view and puts a layout around it if found.

Layout was renamed to _layout because it is a partial. Also partials don’t use the layout feature (so layout doesn’t have a layout)
