Version 0.4 Started on the UserInterface class and startes the process of making a userfirendly and responsive UI. I added the nesessary verifying methods getInteger, getString, getHours, getMinutes and getSeconds to validate the user input. These will be used when the program needs the user to input informaton, and make sure that the correct variable type is providet in the correct place. Also made som small changes to register class and added a throws illegalargumentexception in the addDeparture function as i needed that to make the function throw the illegalargumentexception thrown by the Traindeparture class constructor when an invalid input was given
