Merge branch 'lee' into develop
.gitignore: added Gemfile.lock (let gemspec specify the gem versions)
Moved file loading responsibility to executable codebadges

- badges.rb:
	- changed get_badges_from_file into get_users_badges
		- now only takes user_array and returns hash
		- eliminated all file handling (loading user list)
	- moved read_files to /bin/codebadges executable (now get_users_array_from_file)
- bin/codebadges
	- moved read_file from badges.rb into executable as get_users_array_from_file
  - now only calls get_users_badges from CodeBadges class
refactored bin/codebadges: use block form for file open/close
Modified tests to handle multiple users	(not file input)

- call CodeBadges.get_users_badges instead of from file
Merge pull request #9 from ISS-SOA/ray
