With an updated eslint version and the addition of eslint-config-openstack and eslint-plugin-angular, there are several more stylistic guidelines to follow. However, this is what other OpenStack angular projects follow such as Horizon. Some notable changes are: * Wrapped javascript content in anonymous functions. This is a safeguard to keep the code from conflicting with other variables with the same name in other scripts on the same page. * Explicitly inject dependencies and have controllers, factories, etc as explicitly declared functions. * Use angular "controller as" syntax instead of assigning variables to $scope. * Added eslint rule that requires JSDoc for every function declaration. Note these are mainly stylistic changes and all the functionality of RefStack should remain the same. Change-Id: I044b1f473d589681a2ae9d2704700dd85687cbb6
