JS代码格式化和语法着色V2
更新时间：2006年10月14日 00:00:00 作者：
升级到第二版，开一贴以示庆贺，哈哈哈
自 Ver1.1 升级内容
1. 增加函数列表
2. 增加函数 Export 功能
3. 增加函数依存关系分析 （这个功能个人未见其他软件实现过，自己创意，问题多多，目前分析能力还是比较有限的，只能分析全局函数依存关系，可能在复杂代码的情况下出现 bug）
4. 修正 for 语句分析 bug
5. 修正 语法折叠的 bug
6. 改进 Collapse All ※ Expand All 函数工作方式，避免行数太大时的死机
7. 改进行号分析机制，避免行数太大时的死机

自 Ver1.1 升级内容
1. 增加函数列表
2. 增加函数 Export 功能
3. 增加函数依存关系分析 （这个功能个人未见其他软件实现过，自己创意，问题多多，目前分析能力还是比较有限的，只能分析全局函数依存关系，可能在复杂代码的情况下出现 bug）
4. 修正 for 语句分析 bug
5. 修正 语法折叠的 bug
6. 改进 Collapse All ※ Expand All 函数工作方式，避免行数太大时的死机
7. 改进行号分析机制，避免行数太大时的死机
