Use TDD to create a Candidate class that responds to the following interaction pattern.
pry(main)> require './lib/candidate'
=> true
pry(main)> diana = Candidate.new({name: "Diana D", party: :democrat})
=> #<Candidate:0x00007fd83736dbe0...>
pry(main)> diana.name
=> "Diana D"
pry(main)> diana.party
=> :democrat
pry(main)> diana.votes
=> 0
pry(main)> diana.vote_for!
pry(main)> diana.vote_for!
pry(main)> diana.vote_for!
pry(main)> diana.votes
=> 3
pry(main)> diana.vote_for!
pry(main)> diana.votes
=> 4Use TDD to create a Race class that responds to the following interaction pattern.
The register_candidate! method must take a Hash as an argument and return an instance of Candidate.

The vote_counts method should return a hash with each candidate's name as a key and their count of votes as the value.

The open? method returns a boolean indicating whether the race is open or not. A race should be open by default.
The close! method should close the race (should no longer be open).
The winner method should return false if the race is still open. It should return the candidate with the most votes if not open. If there is a tie, it should return any candidate with the highest number of votes.
The tie? method should return a boolean indicating if two or more candidates received the highest number of votes.
Additionally, you should use TDD to implement a method for the Election class called winners that will return an array of the Candidate objects that represents the winner from each race. If the race is a tie or is still open, no winner should be returned for that race.
