+/**
+ * <p>
+ * This class represents a data model for choosing a component for handing a
+ * given {@link Intent}. The model is responsible for querying the system for
+ * activities that can handle the given intent and order found activities
+ * based on historical data of previous choices. The historical data is stored
+ * in an application private file. If a client does not want to have persistent
+ * choice history the file can be omitted, thus the activities will be ordered
+ * based on historical usage for the current session.
+ * <p>
+ * </p>
+ * For each backing history file there is a singleton instance of this class. Thus,
+ * several clients that specify the same history file will share the same model. Note
+ * that if multiple clients are sharing the same model they should implement semantically
+ * equivalent functionality since setting the model intent will change the found
+ * activities and they may be inconsistent with the functionality of some of the clients.
+ * For example, choosing a share activity can be implemented by a single backing
+ * model and two different views for performing the selection. If however, one of the
+ * views is used for sharing but the other for importing, for example, then each
+ * view should be backed by a separate model.
+ * </p>
+ * <p>
+ * The way clients interact with this class is as follows:
+ * </p>
+ * <p>
+ * <pre>
+ * <code>
+ *  // Get a model and set it to a couple of clients with semantically similar function.
+ *  ActivityChooserModel dataModel =
+ *      ActivityChooserModel.get(context, "task_specific_history_file_name.xml");
+ *
+ *  ActivityChooserModelClient modelClient1 = getActivityChooserModelClient1();
+ *  modelClient1.setActivityChooserModel(dataModel);
+ *
+ *  ActivityChooserModelClient modelClient2 = getActivityChooserModelClient2();
+ *  modelClient2.setActivityChooserModel(dataModel);
+ *
+ *  // Set an intent to choose a an activity for.
+ *  dataModel.setIntent(intent);
+ * <pre>
+ * <code>
+ * </p>
+ * <p>
+ * <strong>Note:</strong> This class is thread safe.
+ * </p>
