使用方式，參考以下groovy代碼：

//functions.sc 內容

import static com.findsrc.bitlight.BitLightUtil.*

def Log = { it ->println it }

def GetTime = {it-> return GetTime(it,600) }

final ROOT='/Users/rainy/Documents'

//functions.sc 內容

//include上級目錄的functions.sc

#include(../functions.sc)

ROOT+'/'+GetYmd(rowdata.datetime)+'/'+rowdata.contractId+'.dat'
