/**
 * 步骤：
 * 1. 创建start()函数
 * 2. 创建变量imagePath储存图片路径：C:\Users\Zhuanz\Desktop\AIStoryBoard\static\漫画\image\鬼-巷第001卷\第一章\0004_鬼-巷第001卷.jpeg
 * 3. 创建变量outputDir储存输出目录：C:\Users\Zhuanz\Desktop\AIStoryBoard\static\漫画\image\鬼-巷第001卷\第一章\test
 * 4. 调用comic-text-detector.js生成文字遮罩图(保存到test/tmp目录) 
 * 5. 调用check-reg.js检测格子,并绘制出来格子图片
 * 6. 调用merge-image.js合并带绿色框的文字区域图片和格子图片
 * 7. 调用cut-check.js切割黑线(不是绿线的)格子(按从右到左、从上到下顺序)
 * 8. 调用cut-dialog-block.js 切割绿色线框
 * 9. 调用ocr.js依次识别文件夹下的图片，生成识别结果的json文件
 * 10. 调用sort-dialog.js整理语句块的排序，返回结果。
 * 11. 调用sort-sentence.js整理所有check文件夹下的识别结果json，根据x1越大越靠前的原则排序，生成check.txt文件
 * 12. 使用generate-dialog-json.js 接收sort-dialog.js返回的结果，生成对话JSON，保存到outputDir目录
