**Partially** implemented spam filtering with Akismetor
  Code for Akismet(or) has been added in:
    - comment model
    - comment controller
    - routes [for marking as spam/not spam manually]
    - views to reflect changes, although this naturally does
      not affect the logic
  The system is currently in a pseudo working state - in the it will
  not crash out in normal operation - although submitting comments
  will have no effect, and comments which exist are no longer
  displayed.

  I believe that the current lack of functionality lies in either
  the new routing added for comments, the akismet service itself, or
  perhaps naivety in my modification of the controller.

  As a result of the above, cucumber and rspec tests for the
  comments are currently failing.
