    Este interface, con el tiempo deberia ir al SPI.

    Tendria que sustituir a:

    - FeatureManager

    - FeatureTypeManager

    - SpatialManager

    como mecanismos para guardar los datos mientras se esta en edicion.

    Habria que eliminar estos managers del DefaultFeatureStore y sustituirlos

    por este.

    En una primera implementacion, se mantendrian estos managers como parte interna

    de la implementacion del MemoryEditingManager.
