Single Report: Create Angular Resource for Comments

[joshuapowell]

In order to query the Comments for a Report we need to make sure that we have an Angular Resource to access content through the Comment API endpoint. Functionality needs to cover generic Angular Resource settings:

• Query
• Get
• Save
• Update
• Delete

The API endpoint is secured in a way that even if an unauthorized user were to send a "DELETE" to the Comment API endpoint, the API knows to check to see if they authorized to that prior to editing or deleting said Comment feature from the database. It should either return a 401 or 403 depending on the interaction and circumstances.
