	/**
     * Creates a new operation that recursively imports the entire contents of the
     * specified root file system object.
     * <p>
     * The <code>source</code> parameter represents the root file system object to 
     * import. All contents of this object are imported. Valid types for this parameter
     * are determined by the supplied <code>IImportStructureProvider</code>.
     * </p>
     * <p>
     * The <code>provider</code> parameter allows this operation to deal with the
     * source object in an abstract way. This operation calls methods on the provider
     * and the provider in turn calls specific methods on the source object.
     * </p>
     *  <p>
     * The default import behavior is to recreate the complete container structure
     * for the contents of the root file system object in their destination. 
     * If <code>setCreateContainerStructure</code> is set to false then the container 
     * structure created is relative to the root file system object.
     * </p>
     * 
     * @param containerPath the full path of the destination container within the
     *   workspace
     * @param source the root file system object to import
