"""
对Selenium2Library element操作的健壮性封装、普通操作不受影响.
每个element操作方法生成一个操作对象
''' 2类对象:
father类型: fatherName=None eleMethodName=webObj.browserName，
一般在webObj创建时配套创建, _eleMethod_objDc中记录，形如{fatherName:{}}
非father型: fatherName!=None eleMethodName=webObj.b下的eleMethodName
在webObj中以"self.w.eleMethodName()"形式使用、首次使用时创建
_eleMethod_objDc中记录，形如{fatherName:{eleMethodName:eleMethodObj}}
