/**

As a user I want to travel by train to a certain city. I can give this program

the city I depart from and the city I want to arrive at.

The program should give us the route we need to take, that is: which stations

we need to go to. For example, if we want to go from Amsterdam to Arnhem it

should give us [Amsterdam, Utrecht, Arnhem]

Furthermore it should also tell us the distance of a route and the cost of our

train ticket. A train ticket costs about 19 eurocents per kilometer
