Working on refactoring BallotStore.java and Supervisor.java by implementing Precinct.java
Added some status getters for these machines to cleanup some code (BallotScannerMachine.java, SupervisorMachine.java, VoteBoxBooth.java)
Separated PinTimeStamp.java from BallotStore.java. Working on implementing PIN functionality directly into Model.java
Regarding #38 #39:

-Resolved all of the syntax errors from moving functionality.
-PINs exist in Model.java but probably don't function properly yet.
-Changed the language in Precinct.java from 'challenged' to 'spoiled' as the default and deleted challengeBallot().
-Fixed some old code in ActiveUI.java that was giving syntax errors.
-Added hashing code into Model.java, but that probably doesn't function yet either until it's formally introduced.
