Introducing helper.coffee

This file will be the base for small common services/resources etc. which can be used by any component and not adding any new dependency.
Currently it only has baseurl as a common place to generate the base url which will be used by many components

h/js/helper.coffee

+baseURL = ($document) ->
+  baseUrl = $document[0].baseURI
+
+  # Strip an empty hash and end in exactly one slash
+  baseUrl = baseUrl.replace /#$/, ''
+  baseUrl = baseUrl.replace /\/*$/, '/'
+
+  baseUrl
+
+angular.module('h.helper', [])
+  .factory('baseurl', ['$document', baseURL])
