- Updated the Node interface and its implementations to include a strength() function. This is a double value between 0 and 1 representing the percent activation.

- Updated the PlayerModel to fix a bug in the high score tracking.
- Created HighScoreDialog.java, which displays the high scores from a PlayerModel. In the future, it will have a "New Game" button so that it can be used to transition between games.
