Added ability to store optional member data alongside the leaderboard data.
:with_member_data is now a valid request option when retrieving leader data.
leaderboard 2.0.6 (2012-04-26)
Added accessor for reverse option so that you can set reverse after creating a leaderboard to see results in either highest-to-lowest or lowest-to-highest order.
leaderboard 2.0.5 (2012-03-14)
Added rank_members(members_and_scores) and rank_members_in(leaderboard_name, members_and_scores) allowing you to pass in some variable number of member_name, score and so on or an actual array of those data items. Use this method to do bulk insert of data, but be mindful of the amount of data you are inserting since a single transaction can get quite large.
leaderboard 2.0.4 (2012-02-29)
Added page_for(member, page_size = DEFAULT_PAGE_SIZE) and page_for_in(leaderboard_name, member, page_size = DEFAULT_PAGE_SIZE) calls to allow you to determine the page where a member falls in the leaderboard
leaderboard 2.0.3 (2012-02-22)
Added :reverse => false to Leaderboard::DEFAULT_OPTIONS to support leaderboards sorted from lowest to highest score instead of highest to lowest score. (Thanks @siuying)
leaderboard 2.0.2 (2012-02-03)
Fix for checking to see if a member actually exists in the leaderboard for the around_me calls
Return appropriate nil in data returned for calls such as percentile_for and ranked_in_list for non-existent members
