add google-simplified.mustache and sphinx-simplified.mustache

[johnjim0816]

I delete extra blank lines for google format and save as "google-simplied", so that it seems look like better at least for me. An example in python shown as following: '''[summary] Args: init_status ([type]): [description] aim_status ([type]): [description] x_width ([type]): [description] y_width ([type]): [description] Returns: [type]: [description] ''' And also for sphinx: '''[summary] :param init_status: ([type]): [description] :param aim_status: ([type]): [description] :param x_width: ([type]): [description] :param y_width: ([type]): [description] :return: ([type]): [description] '''
