+/**
+ * Adds support for sharing features to a CalDAV server.
+ *
+ * Note: This feature is experimental, and may change in between different
+ * SabreDAV versions.
+ *
+ * Early warning: Currently SabreDAV provides no implementation for this. This
+ * is, because in it's current state there is no elegant way to do this.
+ * The problem lies in the fact that a real CalDAV server with sharing support
+ * would first need email support (with invite notifications), and really also
+ * a browser-frontend that allows people to accept or reject these shares.
+ *
+ * In addition, the CalDAV backends are currently kept as independent as
+ * possible, and should not be aware of principals, email addresses or
+ * accounts.
+ *
+ * Adding an implementation for Sharing to standard-sabredav would contradict
+ * these goals, so for this reason this is currently not implemented, although
+ * it may very well in the future; but probably not before SabreDAV 2.0.
+ *
+ * The interface works however, so if you implement all this, and do it
+ * correctly sharing _will_ work. It's not particularly easy, and I _urge you_
+ * to make yourself acquainted with the following document first:
+ *
+ * https://trac.calendarserver.org/browser/CalendarServer/trunk/doc/Extensions/caldav-sharing.txt
+ *
+ * An overview
+ * ===========
+ *
+ * Implementing this interface will allow a user to share his or her calendars
+ * to other users. Effectively, when a calendar is shared the calendar will
+ * show up in both the Sharer's and Sharee's calendar-home root.
+ * This interface adds a few methods that ensure that this happens, and there
+ * are also a number of new requirements in the base-class you must now follow.
+ *
+ *
+ * How it works
+ * ============
+ *
+ * When a user shares a calendar, the updateShares() method will be called with
+ * a list of sharees that are now added, and a list of sharees that have been
+ * removed.
+ * Removal is instant, but when a sharee is added the sharee first gets a
+ * chance to accept or reject the invitation for a share.
+ *
+ * After a share is accepted, the calendar will be returned from
+ * getUserCalendars for both the sharer, and the sharee.
+ *
+ * If the sharee deletes the calendar, only their share gets deleted. When the
+ * owner deletes a calendar, it will be removed for everybody.
+ *
+ *
+ * Notifications
+ * =============
+ *
+ * During all these sharing operations, a lot of notifications are sent back
+ * and forward.
+ *
+ * Whenever the list of sharees for a calendar has been changed (they have been
+ * added, removed or modified) all sharees should get a notification for this
+ * change.
+ * This notification is always represented by:
+ *
+ * Sabre\CalDAV\Notifications\Notification\Invite
+ *
+ * In the case of an invite, the sharee may reply with an 'accept' or
+ * 'decline'. These are always represented by:
+ *
+ * Sabre\CalDAV\Notifications\Notification\Invite
+ *
+ *
+ * Calendar access by sharees
+ * ==========================
+ *
+ * As mentioned earlier, shared calendars must now also be returned for
+ * getCalendarsForUser for sharees. A few things change though.
+ *
+ * The following properties must be specified:
+ *
+ * 1. {http://calendarserver.org/ns/}shared-url
+ *
+ * This property MUST contain the url to the original calendar, that is.. the
+ * path to the calendar from the owner.
+ *
+ * 2. {http://sabredav.org/ns}owner-principal
+ *
+ * This is a url to to the principal who is sharing the calendar.
+ *
+ * 3. {http://sabredav.org/ns}read-only
+ *
+ * This should be either 0 or 1, depending on if the user has read-only or
+ * read-write access to the calendar.
+ *
+ * Only when this is done, the calendar will correctly be marked as a calendar
+ * that's shared to him, thus allowing clients to display the correct interface
+ * and ACL enforcement.
+ *
+ * If a sharee deletes their calendar, only their instance of the calendar
+ * should be deleted, the original should still exists.
+ * Pretty much any 'dead' WebDAV properties on these shared calendars should be
+ * specific to a user. This means that if the displayname is changed by a
+ * sharee, the original is not affected. This is also true for:
+ * * The description
+ * * The color
+ * * The order
+ * * And any other dead properties.
+ *
+ * Properties like a ctag should not be different for multiple instances of the
+ * calendar.
+ *
+ * Lastly, objects *within* calendars should also have user-specific data. The
+ * two things that are user-specific are:
+ * * VALARM objects
+ * * The TRANSP property
+ *
+ * This _also_ implies that if a VALARM is deleted by a sharee for some event,
+ * this has no effect on the original VALARM.
+ *
+ * Understandably, the this last requirement is one of the hardest.
+ * Realisticly, I can see people ignoring this part of the spec, but that could
+ * cause a different set of issues.
+ *
+ *
+ * Publishing
+ * ==========
+ *
+ * When a user publishes a url, the server should generate a 'publish url'.
+ * This is a read-only url, anybody can use to consume the calendar feed.
+ *
+ * Calendars are in one of two states:
+ * * published
+ * * unpublished
+ *
+ * If a calendar is published, the following property should be returned
+ * for each calendar in getCalendarsForPrincipal.
+ *
+ * {http://calendarserver.org/ns/}publish-url
+ *
+ * This element should contain a {DAV:}href element, which points to the
+ * public url that does not require authentication. Unlike every other href,
+ * this url must be absolute.
+ *
+ * Ideally, the following property is always returned
+ *
+ * {http://calendarserver.org/ns/}pre-publish-url
+ *
+ * This property should contain the url that the calendar _would_ have, if it
+ * were to be published. iCal uses this to display the url, before the user
+ * will actually publish it.
+ *
+ *
+ * Selectively disabling publish or share feature
+ * ==============================================
+ *
+ * If Sabre\CalDAV\Property\AllowedSharingModes is returned from
+ * getCalendarsByUser, this allows the server to specify whether either sharing,
+ * or publishing is supported.
+ *
+ * This allows a client to determine in advance which features are available,
+ * and update the interface appropriately. If this property is not returned by
+ * the backend, the SharingPlugin automatically injects it and assumes both
+ * features are available.
