V3 Ch10 Added comments model
Added comments assocation method (a method that you call on the collection COOL). It works on version he is wokring on but to get it to not error out I need to use the peepcode xml feed in blog_spec.rb
Stubbed out network feed to use local feed. No longer need comment in blog_spec
V3 Ch13 Added a POR factory to spec/support
Blog #index view, blog_controller calls and blog scope plus fixture
