 ### 训练日志模板：
 * 输出文件：模板、单词词频列表
 	* 运行脚本的的命令：
-		* python ft\_tree.py -FIRST\_COL 0 -NO\_CUTTING 1 -CUTTING\_PERCENT 0.3 -data\_path ./training.log -template_path ./output.template -fre\_word\_path ./output.fre -picture\_path ./tree.png -leaf\_num 4 -short\_threshold 5 -plot\_flag 1

 	* 参数样例：
 	   * FIRST\_COL 每行日志从第几列作为输入，默认为0
 	   * NO\_CUTTING = 0 #初步设定1时，是前30% 不剪枝 ,全局开关， 当其为0时，全局按照min_threshold剪枝
