‘ 堆栈在树形结构中使用的实例
‘
‘-------------------------------------------------------------------------------
‘ 本实例实现一下功能：
‘ (1) 树形结构中，按级数汇总数量，即每级汇总该级下全部数量
‘ (2) 按树形结构设置Excel的数据分组及分级显示
‘ (3) 使用方框与连接线绘制树形，类似TreeView效果
‘-------------------------------------------------------------------------------
‘ 原始数据中，有全部数形结构数据，各节点唯一的编号、能指示节点所在级数的符号、
‘ 节点的名称、需要统计的数量。该树形结构各分支的级数不确定，仅在各分支的末梢节点有
‘ 待统计的数量数据。
‘-------------------------------------------------------------------------------
‘ 本代码采用字典对象模拟堆栈，对原始数据循环一次扫描完成统计计算并绘制树形图，
‘ 可学习到堆栈、字典对象、结构图绘制、数据分组分级显示、代码操控单元格公式等多方面
‘ 内容。
‘ 本实例可应用于材料清单（BOM）的统计、公司结构绘制等多种实践。
