// @note 2018.06.15-V1.4 修复在CSDN代码中，高亮处理之后导致的多了一部分文字的问题；减少了多次调用可能出现的冲突问题；依旧添加G键也是高亮效果
// @note 2018.06.04-V1.3 1.修复百度翻页之后偶尔不自动高亮的问题；2.新增一定的页面高亮效果的调整；优化关键词的数量，数量到达一定程度，之后的关键词不做高亮处理
// @note 2018.05.31-V1.2 修复由于分词不准的问题导致的丢词问题；修复停止高亮然后又自动启动的问题；修复下划线分割问题；修复左右尖括号转换问题；新增W高亮时复制文字内容
// @note 2018.05.26-V1.1 修复垃圾代码，上个版本真的是垃圾代码，运行又慢，占用又高，还特么定时运行，但就是数据出现很慢，现在应该没有这个问题了
// @note 2018.05.25-V1.0 从百度重定向脚本中拆分出来
// @run-at document-body
