解释如下函数代码：
def metalLink(tkcell,device,linkW=2,linkS=1,location=3,offset=['center',0],tkW=None,padW=None,padL=None,pitch=None,pad1offset=None,**pinset):
'''把device放到tkcell中,并根据设置连线'''
'''PADcell必须用pad画的, 否则需设置padW等参数'''
'''location指device放到哪个PAD的右边, offset有3个值,center, up,down, 指放到pad哪个位置,默认为center,放到pad中间,up指放pad上面,大小写不敏感'''
'''offset为列表, 当设置为center时, value一定是0, 当设置为非center时, eg offset=['up',10]指放到pad上面,离pad 10um'''
'''如果把pin定义成字典, 必须提前定义, 参数前面加**来引用, 或者直接写成,G=11，D=12,S=11...'''
'''写成字典形式: pinset={'G':12,'D':12,'S':11},引用 metalLink2(....,**pinset)'''
