应用举例：有10000个表格文件（都用规则的名称命名，但是有的编号可能有遗漏），平均分配给n个人
如下的代码可以自动生成子文件夹（sub1，sub2，。。。，subn）

This script splits multiple files into segregated folders averagely.
Usage: python seperate.py source destination groupNumber folderFormat
Example: python seperate.py /source /destination 3 sub, which groups files in /source into /destination/sub001/, /destination/sub002/ and /destination/sub003/
Notice subdirectories should be avoided in /source/
