*Filename: google_feeds_api.js
*Description: RSS feed aggrigator/page-block for HVHS minisite
*Version: 1.0.0 (07-20-2009) MM-DD-YYYY
*Website: http://www.louisianahighschools.org
*Author: Christopher Barnette
== STRUCTURE: ====================================================================================
*Explaination: This script is called from the [body.onload] event of every page where
the HVHS Blog RSS feed needs to be embedded. In its original design, the
script has three possible formats in which the RSS feed entries can be
displayed. The format required changes on each of the three page types;
home (case 1), blog (case 2), and interior (case 3). To assist with date
formatting issues, two new methods () have been added to the default
JS Date() object through the prototype() object. RSS Entries coming from
the Google Feeds API are in [JSON] format.
*Custom Functions: initialize_feed_embed()
*Custom Properties: Date.toDDMMYYYYString, Date.toDDDDMMMMDYYYYString
*Custom Arrays: month_names[], weekday_names[]
*RSS Entry Props: title, link, content, contentSnippet, publishedDate, categories[]
*Incl. Frameworks: Google Feeds API (AJAX) -
http://code.google.com/apis/ajaxfeeds/documentation/reference.html
== NOTES: ========================================================================================
*Any other notes or commentary goes here.
