Project Overview.

In this project, you will implement a leaderboard for an imaginary programming competition. For now, the programming competition and leaderboard are simple. Each contestant, who is identified by a name may submit a single solution, which will then be given a numerical score $($this is an integer$).$ The leaderboard is meant to maintain a list of the top M scores $($along with the Contestant's name$)$ that have currently been awarded, No other information needs to be stored at this point.
