/**
* The basic operation is to visit a city for a given number of nights. The name
* of the city, and the number of nights spent there, are added to the journal,
* represented as a String. Each city has a certain hostel cost for staying
* there. If the Backpacker doesn't have enough money, she must sleep at the
* train station for some of those nights. The Backpacker's funds can be
* replenished by calling home. However, the Backpacker's parents are stuck at
* home working full time and may not have much sympathy for the Backpacker
* running out of money while gallivanting around Europe. The amount they send
* is proportional to the number of postcards the Backpacker has sent to them
* since the last time she asked for money. Of course, sending a postcard from a
* city costs money too. If things are so bad that the Backpacker doesn't even
* have enough money to send a postcard home from her current city, we say that
* the Backpacker is SOL (Shit Out of Luck)
