Cassandra Installation and C++ with Auth

I had the opportunity to experiment with Cassandra at one point and figured it was worth sharing my experience with getting started on it. There's a good amount of documentation on it, but figured my distilled learnings here could be helpful for others. At the very basic, I think Cassandra is great, it's a key value store has some origins from the Dynamo paper. I've also worked a lot with DynamoDB so it's interesting to compare, though they aren't completely the same.
