Docker files can now be setup to use multiple images to generate a build pipe line. This allows you to use different images (i.e. official images) vs. a single image with all tools installed. With this change we can remove NPM and Node from the run time image which just needs Apache. We can also seperate the hosting commands from the compilation commands. The current Dockerfile installed apache, node, and npm as well as packages required to install the NPM packages used to _build_ the angular app. Once built all the files are served staticlly via apache. Node and NPM are _not_ needed to host the application. This results in dependencies and commands being mixed up. This change set splits the Dockerfile into two stages: Build and Host The Build stage uses an offical Node image and installs the OS packages needed to run the Grunt tasks. It then copies in the source files and runs Grunt build. The artifacts of this image are located in the dist directory. The Host stage uses a debian:jessie image and installs apache (maybe later we can move to an offical Apache image), it then copies the artifacts from the Build stage into its /var/www/html folder, then configers and starts Apache. Now the steps and dependencies are nicely seperated
