Version 0.1.2A Release

-Added specimen end date calculation
-Added two new classes: CSVHandler and TestFrame to lay the groundwork
for further refactoring
-Eventually TestFrame will be the main hub for information regarding
the... test frame and will pass data to the CSVHandler which will write
to a specified location.  Plan is to write CSVHandler in a manner that
allows it to be used for both the frame panels and lab monitoring
programs.
