 3.  The classes `TomAraya` and `ElvisPresley` also implement the interface, but not the method. Instead, they delegate the method calls to the 
     responsible implementation. The delegate object is defined after the `by` keyword. As you see, no boilerplate code is required.

 # Delegated Properties
 
-Kotlin provides a mechanism of [delegated properties](http://kotlinlang.org/docs/reference/delegated-properties.html) that allow delegating the calls of the property `set` and `get` methods to a certain object.

 The delegate object in this case should have the method `getValue`. For mutable properties, you'll also need `setValue`.
