[keycloak-user] Ionic with keycloak-js sample project

Hi I couldn't find a good sample project with keycloak-js and Ionic anywhere on the internet (there is a very basic example with Cordova on GitHub), so I decided to hack one on my own. In addition, I decided to modularize the starter Ionic tabs project and add ES6 support. The project initializes Keycloak adapter and adds an auth interceptor on $httpProvider for header injection. Hopefully this is useful for someone. Best regards, cen
