Package githubapi implements issues.Service using GitHub API clients.
func NewService(clientV3 *githubv3.Client, clientV4 *githubv4.Client, notifications notifications.ExternalService, router github.Router) issues.Service
NewService creates a GitHub-backed issues.Service using given GitHub clients. It uses notifications service, if not nil. At this time it infers the current user from GitHub clients (their authentication info), and cannot be used to serve multiple users. Both GitHub clients must use same authentication info.
If router is nil, github.DotCom router is used, which links to subjects on github.com.
