[5pt] - Comments resource

[Nemwel-Boniface]

In this milestone I am going to implement the following:

• Generate the comments resource with the rails g scaffold. The fields to be added include:
  • Comment_text
  • Commenter name [OPTIONAL] default is "Anonymous"
  • blog_id
  • date commented
• A comment has to belong to a specific blog. Linked by the blog_id
• Add the update_comments_counter method for a specific blog in the comments model
• Add the comment form to the blog show to allow automatically creating a comment for a blog.
• List all the comments )OPTIONAL). Listing umber of comments only seems better.
