GoogleReaderSource: Retrieve feeds through the Google Reader API.

Description

This function utilizes the (unofficial) Google Reader API to retrieve RSS feeds. The advantage of access RSS feeds through the Google Reader API is that you are not limited by the number of entries a website may included in their feed. That is, Google maintains generally maintains a complete history of entries from the RSS feed. Code was partly taken from Jason Bryer http://bryer.org/2012/retrieving-rss-feeds-using-google-reader Note that the contents of the results will be limited by what the website provides in their feeds. That is, Google does not contain more information per entry then what the website originally provided. If the initial feed contained only excerpts of the article, the feed from Google will too only contain excerpts. Be aware though that for sites that do provide the complete contents of posts will result in potentially very large downloads.
