* We have 3 files that are modified in our local git repository, but we only want to stash 2 of those files. 
* If we use git stash save, git will save all 3 files in the stash. How can we stash only README and TODO?

Create a new leaderboard or attach to an existing leaderboard named 'highscores':

   ruby-1.8.7-p302 > highscore_lb = Leaderboard.new('highscores')
   => #<Leaderboard:0x1018e4250 @page_size=25, @port=6379, @host="localhost", @redis_connection=#<Redis client v2.1.1 connected to redis://localhost:6379/0 (Redis v2.1.10)>, @leaderboard_name="highscores"> 
   
If you need to pass in options for Redis, you can do this with the redis_options parameter:

  redis_options = {:host => 'localhost', :port => 6379, :password => 'password', :db => 'some_redis_db'}
  highscore_lb = Leaderboard.new('highscores', redis_options[:host], redis_options[:port], Leaderboard::DEFAULT_PAGE_SIZE, redis_options))
