Scala demo with Tuple and Option and Pattern Matching and Exception

The Tuple is good for returning multiple values without creating a class. The maximum number of values is currently 22. Which means that there is actually a type called Tuple22! The option is a good way to avoid NullPointer-Exceptions. The Pattern Matching is good for evaluating values. The Exception handling is using pattern matching! Enjoy! :-) Feel free to comment or ask questions.
