Added a "Home" button to the Library activity, made a path from that
button to the HomeScreen activity, and placed a temp background for said
activity.  Also, if anyone is planing on programming anything in either
the xml or java files, please comment, even if it's a simple function. I
want to leave this code as clean as possible.
commenting in java is the same as C++ just       // comment
commenting in xml is a little different          <!-- comment -->

Thanks - John
