Demo

I decided not to create the exact same app as the Railscast, but did a blog instead. Based on notes from class and from watching the Railscast several times, I feel I have a good feel for using Mongo.  I chose to use the 4.0.0(beta1) version of Mongoid, along with Rails 4.1.0.  Installation of mongoid was fairly easy on my Linux (Ubuntu 32-bit) environment.

I ran into nasty errors when trying to include the Paranoia and Versioning frameworks mentioned in the railscast, so I did not include them.  Did some poking around and found that those frameworks were removed from the 4.0.0 release, as described in the changelog for mongoid here:  https://github.com/mongoid/mongoid/blob/master/CHANGELOG.md
(Items #2432 and 2433 pertain)
