Createcharacters

We have created the database, created the characters views,models, controllers, factories, and tests. All things work except for the user_views_all_characters_spec on the portion that mentions the matchups. We also did not edit the user_creates_a_matchup_spec.rb since it is not in our domain. 
Should be `Character.find_or_create_by`, otherwise it'll try to duplicate characters in your DB if you run `rake db:seed` multiple times.
