added categories to user schema
made res.send data.lifeEvents into a json that sends lifeEvents and categories. updated the ajax request on client respectively. now to fix categories service
i want to watch for changes on eventService.categories.. from the categoryService. not working yet
injected categoryService into EventService
add category, now i use a watch on rootscope, while injecting eventservice into it, rather than other way around. route + mongodb update works on server
deleteCategory works now, on front end with an options list, and backend with a route. now add a safety so user can't delete the default categories
won't let user delete a default category
