I've read of course the racket guide and reference but the examples I found
there are (for me) completely useless:<br>
I'm not interested in how to create class hierarchies. The only thing I want to
know is<br>
how to create a class and how to create for example 3 instances of the class. I’d
like to know what exactly the “size” parameter is and if I have to use it.</span></div>
