All of the files have been commented except for package.json (can't place comments in a .json file).

package.json

This is the file that npm uses. It should describe exactly how your project should operate.

  Build our project in production mode.  Important thing to note here is that it
  references a module that is a project dependency (webpack).  Avoid doing scripts
  like "webpack -p" because that assumes that the developer has installed webpack
  globally.  It also means that they may end up using a version of webpack that
  the original author never intended on using.

  /*
  Lists all 3rd party dependencies required by the project (including webpack).  
  These dependencies are fetched from the npm repository using the "npm install"
  command and placed in the node_modules directory (never commit this directory).  
  This method for pulling in dependencies ensures that you get the correct version
  of all the dependencies.
