Implement a meetup api events call

[mbach04]

When I type /meetups in a specific channel (ie. Hampton Roads) I should get a link to the HR Operation code page and it's next (n) events.

@mbach04, when this is in place, I would want to find ways we could automatically populate Google Calendar with Meetup events as well. That may belong in an issue outside this repository.

Yea - that will be a separate project. https://github.com/OperationCode/event_aggregator has been created.

@mbach04, I am working on adding meet ups information to the android app, so most of the logic for this will be created already (in Java, but it shouldn't be hard for me to turn it into JS). I will likely start working on this slash command in the next couple of weeks.
