Wrote the save method, waiting on some stuffs in Person to have it
finally finished so for now the People writing stuff is commented out.
Most of the save file writing is just a copy-pasta.  Wrote some
toString() methods, getSaveDescription(), and one shorthandToString()
which is used from Relationship in People's toString().  In Controller
you can see a getRelationshipTypeUnderID() and getPersonUnderID()
method.  Also finished up some reading code so now all we are really
waiting for is the view.  Thought I'd finish up that code so Drew will
be able to use working code to see if his stuff is working right.  I
think people needs just needs some work done in getSaveDescription(),
removeRelationship() and Controller needs just a bit more.
