Activity implementation code for Sugar-based activities

Each activity within the OLPC environment must provide two dbus services. The first, patterned after the

sugar.activity.activityfactory.ActivityFactory

class is responsible for providing a "create" method which takes a small dictionary with values corresponding to a

sugar.activity.activityhandle.ActivityHandle

describing an individual instance of the activity.

Each activity so registered is described by a

sugar.activity.bundle.Bundle

instance, which parses a specially formatted activity.info file (stored in the activity directory's ./activity subdirectory). The

sugar.activity.bundlebuilder

module provides facilities for the standard setup.py module which produces and registers bundles from activity source directories.

Once instantiated by the ActivityFactory's create method, each activity must provide an introspection API patterned after the

sugar.activity.activityservice.ActivityService

class. This class allows for querying the ID of the root window, requesting sharing across the network, and basic "what type of application are you" queries.
