Construct a NodeProto.

    Arguments:
        op_type (string): The name of the operator to construct
        inputs (list of string): list of input names
        outputs (list of string): list of output names
        name (string, default None): optional unique identifier for NodeProto
        doc_string (string, default None): optional documentation string for NodeProto
        domain (string, default None): optional domain for NodeProto.
            If it's None, we will just use default domain (which is empty)
        **kwargs (dict): the attributes of the node.  The acceptable values
            are documented in :func:`make_attribute`.
