A Loader designed to retrieve data from a ContentProvider. This class implements the Loader protocol in a standard way for querying cursors, building on AsyncTaskLoader to perform the cursor query on a background thread so that it does not block the application's UI.
A CursorLoader must be built with the full information for the query to perform, either through the CursorLoader(Context, Uri, String[], String, String[], String) or creating an empty instance with CursorLoader(Context) and filling in the desired paramters with setUri(Uri), setSelection(String), setSelectionArgs(String[]), setSortOrder(String), and setProjection(String[]).
