将清单中的"元件值\t元件位号"分裂为"元件位号\t元件值",每个元件一行

在BOM中,清单的格式一般有物料编码,物料描述,元件位号,元件数量,将物料描述简化成一个值,再将这列与元件位号列提取出来,保存到"value+refs.txt"文件中,格式为

元件值\t位号1 位号2 ... 位号n 位号之间的分隔符为1个空格

将下面的脚本复制,保存为"reflist.py"文件,与"value+refs.txt"文件放在同一目录中,操作系统中要先安装有python2(python3未验证),运行此脚本,就会将"value+refs.txt"中的元件按第行一个的格式排列,输出"reflist.txt"文件,此文件就可以直接用作loadBomValue2PCB.bas的输入,将清单中的值导入到PCB中
