Module loaders work

[minniewong]

Our final solution should meet the following criteria:

• We should have the ability to use ES6 syntax in all of our app files
• All of our app files should be imported and not use global variables
  • Forces us to decouple our modules and stick to consistent design patterns
  • Allows us to eliminate dead code
• All dependencies should be imported where used, and not assigned to global variables
  • Gives visibility into where dependencies are used
    Allows us to remove or replaces dependencies when needed
• All scripts should be bundled into "app" and "vendor" bundles
  • Reduces the number of HTTP requests
  • Allows us to cache dependencies and app code separately
  • Allows us to apply minification and other transforms to all scripts
• We should have a manifest of all of our dependencies in package.json
  • Provides a record for ourselves and contributors to know which dependencies are being used
  • Allows us to use tools to analyze and optimize our dependency graph
  • Allows us to apply security updates, bug fixes and new features from our dependencies quickly
  • Reduces the amount of third party code committed to our repo
