Zip Code

[katie291100]

Provide documented code for a working implementation of the game that meets the
remit, requirements and concrete architecture for Assessment 2. Your code
comments should highlight new or extended sections of code, and should be
consistent with your change report. Code can be submitted in the zipfile, or via a link
to a repository with a verifiable date before the hand-in deadline. An executable JAR
of the game, that includes all external dependencies, must also be included in the
zipfile. (15 marks)
