Feature: Document.comments

In order to operate on comments added to a document

As a developer using python-docx

I need access to the comments collection for the document

And I need methods allowing access to the comments in the collection

Scenario Outline: Access document comments

Given a document having <a-or-no> comments part

Then document.comments is a Comments object

Examples: having a comments part or not

Scenario Outline: Comments.__len__()

Given a Comments object with <count> comments

Then len(comments) == <count>

Examples: len(comments) values

Scenario: Comments.__iter__()

Given a Comments object with 4 comments

Then iterating comments yields 4 Comment objects

Scenario: Comments.get()

Given a Comments object with 4 comments

When I call comments.get(2)

Then the result is a Comment object with id 2
