2nd Sprint - created 30/08/2018

transaction type field with enum for credit and debit and write tests rename bank to purse generate seed data - make lots of transactions with type, description and money

3rd Sprint - created 06/09/2018

make seed data have different dates (TEST!!) create a main Application class that when run will print a list of all the transactions in chronological order (TEST!)

This is entire Budjen class with main method. Cannot change this!

public class Budjen {
    public static void main(String[] args) {
        new Application().start();
    }
}

Classes should only have one purpose and at the moment Application is used for many things. Application should delegate to other classes using dependency fields. Use TDD to create the extra classes.

Make sure you test the Orderer and the TransactionFormatter! You may attempt to test the Application class too as extra credit (not that there's a grading system) - but don't fret if you get stuck on that one.
