This project was generated with angular-cli version 1.0.0-beta.19-3.
This project is used for the November, 2016 ng-columbus meetup. The corresponding presentation slides for this project can be found here: ng2-modules slides
This presentation discusses angular2 NgModule usages and patterns as well as a brief example of how to use es2015 Typescript modules for import and export. This project is quite contrived and is meant solely to focus on the essentials of getting modules to work.
