Adding post examples

To query the database for posts, we need to add some post examples. This has to be done on the server, as we want to add them persistently. To add an example post, perform the following steps:

1. We create a file called main.js inside our my-meteor-blog/server folder. Inside this file, we will use the Meteor.startup() function to execute the code on the start of the server.
2. We then add the post example, but only when the collection is empty. So to prevent this, we add them every time we restart the server, as follows:

   Meteor.startup(function(){
   
     console.log('Server started');
   
     // #Storing Data -> Adding post examples
     if(Posts.find().count() === 0) {
   
       console.log('Adding dummy posts');
       var dummyPosts = [
         {
           title: 'My First entry',
           slug: 'my-first-entry',
           description: 'Lorem ipsum dolor sit amet.',
           text: 'Lorem ipsum dolor sit amet...',
           timeCreated: moment...
