/**
* Order Delivery Date Pro for WooCommerce
*
* Send data to the ICS files.
*
* Variables used in this script:
* $summary - text title of the event
* $datestart - the starting date (in seconds since unix epoch)
* $dateend - the ending date (in seconds since unix epoch)
* $address - the event's address
* $uri - the URL of the event (add http://)
* $description - text description of the event
* $filename - the name of this file for saving (e.g. my-event-name.ics)
*
* Notes:
* - the UID should be unique to the event, so in this case I'm just using
* uniqid to create a uid, but you could do whatever you'd like.
*
* - iCal requires a date format of "yyyymmddThhiissZ". The "T" and "Z"
* characters are not placeholders, just plain ol' characters. The "T"
* character acts as a delimeter between the date (yyyymmdd) and the time
* (hhiiss), and the "Z" states that the date is in UTC time. Note that if
* you don't want to use UTC time, you must prepend your date-time values
* with a TZID property. See RFC 5545 section 3.3.5
*
* - The Content-Disposition: attachment; header tells the browser to save/open
* the file. The filename param sets the name of the file, so you could set
* it as "my-event-name.ics" or something similar.
*
* - Read up on RFC 5545, the iCalendar specification. There is a lot of helpful
* info in there, such as formatting rules. There are also many more options
* to set, including alarms, invitees, busy status, etc.
