Added oscillation in the x direction
Finished Oscillation plus dynamic box size

The box size is now based off of the size of the text. In addition,
both move around together on the canvas with the oscillation.
Further optimized code
Implemented mouse clicking event handling.

The controller now tells all of the objects to check if they were the
one clicked.
