Calendar application and backend for Ubuntu Touch

== Client API ==
Calendaring clients for Ubuntu Touch will use QtMobility api's. Specificially, applications should use QOrganizer and related classes as found here:
http://doc.qt.digia.com/qtmobility/organizer.html.

This is consistent with the approach being used for Contacts, which uses QContacts from QtMobility as specified here: https://wiki.ubuntu.com/Touch/Specs/ContactsService.

Clients should instatiate the default manager (QOrganizerManager) for the Ubuntu Touch platform to access the default backend for the platform.

Example client code can be found here:
http://qt.gitorious.org/qt/qtpim/trees/master/examples/organizer/qmlorganizerlistview

== Backend ==
EDS will be used as the backend for Calendaring, but this will be abstracted by the QOrgranzer classes which provide client access. Clients should not use EDS api's directly, but rather the QOrganizer classes.

On Ubuntu Touch a QOrganizerManagerEngine plugin will be written that interfaces with EDS, and this will be set as the default provider for the platform. Until this plugin is written, there are two engines that can be used for development: an in-memory engine and a JSON-document file engine.
