/* jquery.gcal_flow_121_homepage20190609.txt */
// Version: 1.2.1
// Generated by CoffeeScript 1.3.1

// Function gCalFlow.prototype.parse_date
//	Added "offset=0;" because when in Summer time and looking at times in non-Summer time, the hour was out by an hour. Ignoring the offset corrects this as times are not stored according to BST or not.

// Function gCalFlow.prototype.gcal_url
//	Changed function to handle Google's V3 API
//	Added new option 'apikey'

// Function gCalFlow.prototype.render_data
//	Removed call to gcf-item-update-date as don't use it so unnecessary call.
//	Added code to restrict description to 70 characters max.
//	Added code to delete Map coordinates and Postcode in Location.
//	Added code to restrict weddings displayed to a particular church or to all churches - can't do this in the query string!
//	Added code to hide the header if no weddings found
//	Added IF to amend page header to include the name of the church if specified
//	Changed function to handle Google's V3 API
//	Added code to handle if these fields are blank: ent.summary, ent.description, ent.location
