Step 3 - Contacts Collection

1. Add collections/contacts.js with collection:

   ContactManager.Collections.Contacts = Backbone.Collection.extend({
   model: ContactManager.Models.Contact
   });
   

   and to index.html:

   <script src="app/js/collections/contacts.js"></script>
   

2. Create collections with few models in DevTools and show some methods

   var contacts = new ContactManager.Collections.Contacts([
   {
     id: 1,
     name : 'Terrence S. Hatfield',
     tel: '651-603-1723',
     email: '[email protected]'
   },
   {
     id: 2,
     name : 'Chris M. Manning',
     tel: '513-307-5859',
     email: '[email protected]'
   },
   ])
   

3. All underscore.js methods for Collection
