This bot will allow users to comment on a GitHub issue.
Users should preface messages with '@comment' or '@gcomment'.
You will need to have a GitHub account.
Before running this, make sure to get a GitHub OAuth token.
The token will need to be authorized for the following scopes:
'gist, public_repo, user'.
Store it in the 'github_token.txt' file.
The 'github_token.txt' file should be located at '~/github_token.txt'.
Please input info like this:
'/<username>/<repository_owner>/<repository>/<issue_number>/<your_comment>'.
