示例1: InvalidateInRange
/// <summary>
/// Removes nodes from the tree collection if node range is
/// // partially or entirely within the deleted region.
/// This is needed since parsing is asynchronous and without
/// removing damaged nodes so intellisense will still be able
/// to find them in the tree which actually they are gone.
/// Returns true if full parse required.
/// </summary>
/// <param name="node">Node to start from</param>
/// <param name="range">Range to invalidate elements in</param>
