Note: This plugin is NOT meant to be used on actual website builds. It is just a plugin developer resource.
This plugin demonstrates how Craft plugins can take advantage of Craft’s Element Type APIs.
There are two components to this plugin: calendars and events.
Calendars are implemented similarly to sections, tag groups, category groups, et al. in Craft – there’s nothing too special about them. They simply exist to contain events (and to define those events’ Field Layouts).
Events are implemented as Elements.
