Summary of Changes

• Add MongoDB. It currently points at a local database called test. If you want to play around with it clicking the button GET STUFF FROM Trends/place in Simon's Controller will save a LocationTrend Mongo model to your local Mongo database called test.
• Currently the button Get Stuff from Trends/available pulls objects from Trend model in Mongo, but if you have none saved it will just return a blank object.
• Config.js is now out of .gitignore so be sure not to use it for storing environment vars :) We should be using .env now.

Next steps

• Get MongoDB set up to work in production. In order to do that we'll need a MongoLab DB set up and a way to point to that MongoLab db in production. One way we could do that is add the Mongolab URI as an environmental variable and if you're working on the project locally and don't have the Mongolab URI it will point to test:

var uri = (process.env.MONGOLAB_URI || 'mongodb://localhost/test');
mongoose.connect(uri);

Would anyone like to do some research into MongoLabs and set up a free DB and a few users for us?

:+1: pull request looks good!

MongoLabs should be pretty easy. I can look into it with Kevin and anyone else next time we work on it. We'll probably make a new shared account and call it mks-trendr or something lol. will keep you all updated once that starts happening
