Have written Interface and Test for new Score class
ScoreImpl now passes testGetScore()
added testGetID()
passes testGetID()
added testGetName()
passes testGetName()
Made necessary changes to the way scores are recorded and shared.

Changed the storage method of scores and quizzes from SortedMaps to
Lists, I did this as I realised that two players with the same score
were overwriting each other’s results and two quizzes with the same
name would overwrite each other.
Creating QuizSetupServiceImpl

I haven’t found a way to test it using JUnit as it relys on use input
and console output. I have taken the input using the
System.console().readLine() command.
Added RMI compatibility, new toString/compareTo methods
Started writing main classes to start the server

The server can run at the moment, but the client crashes when it tries
to send a quiz object to the server.
refactor
Created PlayClientImpl & a main for PlayClient
Refactor
getAnswers() now returns a SortedMap
