## beer_me_learnings
After porting beer_me to a mean.js app, I kept seeing "exports": e.g. "exports.foo = function() {console.log('hi');}"
I assumed this had something to do with the way the functions were exposed elsewhere in a mean.js app's codebase.
This assumption was fairly correct, and confirmed after reading: http://www.sitepoint.com/understanding-module-exports-exports-node-js/

I do not understand this line: https://github.com/cpww/beer_me/blob/master/app/controllers/users.server.controller.js#L11
Where does the ".extend" method come from?
So the var "_" is assined the module.exports object from "lodash".
Therefore "_.extend" is accessing the "extend" function from within the "lodash" module.
