NukeCops - VCalendar Export Addon for EventCalendar 2.13

I have written an addon that allows your vistors to export your EventCalendar to thier Palm Pilot or other VCalendar supporting application or device. The current features are as follows: Download all Events, Download Events posted since a date, automatic expiring of VCal files, and if the visitor is logged in the system will automatically keep track of what events they have downloaded by they created a VCal file, but if they don't download it they will have to make a selection by themselves. This addon was test on PHPNuke 7.3 and EventCalendar 2.13, and it is my first addon. If you have any questions or comments please contact me. I would be happy to port this to another calendar module, or if you want to translate the english to another language, let me know so I can add these features.
