Now it prevens cyclic flips and addresses #283

_get_anony_mouse_node_name trails out the leading slash which was causing a problem when it matches between flipped-in rule local node name and new flipping-out rule node name at [here](https://github.com/robotics-in-concert/rocon_multimaster/blob/cyclic_flip/rocon_gateway/src/rocon_gateway/flipped_interface.py#L163).

Would it better to remove [this line](https://github.com/robotics-in-concert/rocon_multimaster/blob/cyclic_flip/rocon_gateway/src/rocon_gateway/master_api.py#L716)?
