This game is based off of the Room Adventure template.  Each "room"
is a different subject and the user is presented with objects to
match up in two different columns.  

The Music "room" isn't the best example to use since the questions
are so long that they overlap the answers.  This prevents the user
from choosing a correct pair unless they are very careful where they
click.

In this example, the mapping of answers is the same from room to room.
This can be changed by creating a new array for each subject that 
lists the order of the answers and using that array to initialize the
Text objects, instead of the order array I use in the setup function
of the Activity class.
