Changes:\r\n1. Removed printing of Adjacency List for greedy algorithm as I felt that it was just annoying.\r\n2. Modified Hospital toString method to indicate when `ExchangePair`s belong to hospitals other than the current hospital.\r\n3. Added `incremental` flag to `runKidneyExchange` so that tests were deterministic.\r\n4. Made `runKidneyExchange` public so that it could be invoked by tests.\r\n5. Moved `KidneyType` enum to public so that it could be used in testing.\r\n6. Added visual dashes to denote cycle composition returned by greedy matching algorithm.\r\n\r\nTesting:\r\n1. Added 5 test cases that should pass for both algorithms.\r\n*Currently, ILP fails on `runKidneyExchangeTest5` and I am hoping you can figure out why after this merges, as I believe it should behave the same was as the greedy implementation.* I think perhaps we implemented moving pairs differently?\r\n2. Added scale test for Greedy algorithm to show that greedy algorithm scales well.","created_at":"2018-11-29T07:41:05Z","updated_at":"2018-11-29T07:57:39Z","closed_at":null,"merged_at":null,"merge_commit_sha":"7b9d31949913c2cfaba3c13a9492f3dd1e07e6c8","assignee":null,"assignees":[],"requested_reviewers":[],"requested_teams":[],"labels":[],"milestone":null,"commits_url":"https://api.github.com/repos/jdn5126/KidneyExchange/pulls/7/commits","review_comments_url":"https://api.github.com/repos/jdn5126/KidneyExchange/pulls/7/comments","review_comment_url":"https://api.github.com/repos/jdn5126/KidneyExchange/pulls/comments{/number}","comments_url":"https://api.github.com/repos/jdn5126/KidneyExchange/issues/7/comments","statuses_url":"https://api.github.com/repos/jdn5126/KidneyExchange/statuses/b7b1ee0c99d4d5f8aa4c19092bae381d83b9cdad","head":{"label":"jdn5126:testsAndPrints","ref":"testsAndPrints","sha":"b7b1ee0c99d4d5f8aa4c19092bae381d83b9cdad","user":{"login":"jdn5126","id":12202465,"node_id":"MDQ6VXNlcjEyMjAyNDY1","avatar_url":"https://avatars0.githubusercontent.com/u/12202465?v=4","gravatar_id":"","url":"https://api.github.com/users/jdn5126","html_url":"https://github.com/jdn5126","followers_url":"https://api.github.com/users/jdn5126/followers","following_url":"https://api.github.com/users/jdn5126/following{/other_user}","gists_url":"https://api.github.com/users/jdn5126/gists{/gist_id}","starred_url":"https://api.github.com/users/jdn5126/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jdn5126/subscriptions","organizations_url":"https://api.github.com/users/jdn5126/orgs","repos_url":"https://api.github.com/users/jdn5126/repos","events_url":"https://api.github.com/users/jdn5126/events{/privacy}","received_events_url":"https://api.github.com/users/jdn5126/received_events","type":"User","site_admin":false},"repo":{"id":155938128,"node_id":"MDEwOlJlcG9zaXRvcnkxNTU5MzgxMjg=","name":"KidneyExchange","full_name":"jdn5126/KidneyExchange","private":false,"owner":{"login":"jdn5126","id":12202465,"node_id":"MDQ6VXNlcjEyMjAyNDY1","avatar_url":"https://avatars0.githubusercontent.com/u/12202465?v=4","gravatar_id":"","url":"https://api.github.com/users/jdn5126","html_url":"https://github.com/jdn5126","followers_url":"https://api.github.com/users/jdn5126/followers","following_url":"https://api.github.com/users/jdn5126/following{/other_user}","gists_url":"https://api.github.com/users/jdn5126/gists{/gist_id}","starred_url":"https://api.github.com/users/jdn5126/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jdn5126/subscriptions","organizations_url":"https://api.github.com/users/jdn5126/orgs","repos_url":"https://api.github.com/users/jdn5126/repos","events_url":"https://api.github.com/users/jdn5126/events{/privacy}","received_events_url":"https://api.github.com/users/jdn5126/received_events","type":"User","site_admin":false},"html_url":"https://github.com/jdn5126/KidneyExchange","description":"EE382V:
