    Description copied from interface: IBaseLabelProvider
    
    Disposes of this label provider. When a label provider is attached to a viewer, the viewer will automatically call this method when the viewer is being closed. When label providers are used outside of the context of a viewer, it is the client's responsibility to ensure that this method is called when the provider is no longer needed.
