Fixes Feed Not Displaying Author Name

[davidsivocha]

By Default, the feed doesn't actually show the author name as it's not loaded

By creating a variable that correctly reads from the article metadata to pull in the JSON of the Author we can present the article author name in the feed.

Thanks! Can you add a fallback if the author.json is not found?

[davidsivocha]

Added a one liner, that creates a basic empty object tree so that it doesn't throw an error

[davidsivocha]

I've refactored now. It will look for an author.json

If one is found it will use that, otherwise it will use the default original behaviou

[jnordberg]

Looks good, tested?

[davidsivocha]

Tested under the following circumstances.

1. author.json not present - Uses default behaviour
2. author.json present with no name field - will display no author data. No errors. behaviour intended
3. author.json present with name field - displays name from author json. Behaviour intended

[davidsivocha]

All test cases compile successfully with wintersmith build flagging no errors
