/*

   Exercise 1: model the following world description using C# classes:

               - There are People, and there are Houses.

               - People have names.

               - Houses have addresses.

               - Houses have owners. An owner is a Person.

​

   Exercise 2: instantiate and use Exercise 1 classes to create a Person p

               and a House h sucha that running something like this:   

               > Console.WriteLine( $"{p.Name} lives in {h.Address}" );

​

               Would output this:

               > Jonas lives in Haus Kahnwald, Widen.

​

   Exercise 3: same than previous, but now just doing this: 

               > Console.WriteLine( $"{p.ToString()}" );
