OOP Intro Exercise 1

Scoreboard
Create a class called Scoreboard that has the following members:
(remember that + means its public)

Scoreboard
----------------------------
+ homeTeamName : String
+ homeTeamScore : int
+ visitingTeamName : String
+ visitingTeamScore : int
----------------------------
+ addHomeGoal() : void
+ addVisitingGoal() : void
+ getScore() : String

addHomeGoal() increments the home team's score by 1
addVisitingGoal() increments the visiting team's score by 1
getScore() returns a formatted string of the current score in 
this format:
Home Team Name: home score
Visiting Team Name: visitors score

Add a TestScoreboard class with a main() method to test your 
Scoreboard:
 - create a Scoreboard
 - assign a home team name and a visiting team name
 - print the score
 - increment one or both scores a couple of times
 - print the score again
