The plot_path ROS package

This ROS package is used to plot the (robot's) path in rviz form a geometry_msgs::PoseStamped topic.

Usage

rosrun the plot_path node.
```
rosrun plot_path plot_path_node /pose_input_topic_name (/path_output_topic_name) (output_path_frame_id)
```
The default path_output_topic_name is /plotted_path, and the default output_path_frame_id is same as the frame_id of the input topic.
Then launch the rviz, create the Path visualization(click the Add button left down.). Then you will see the path shows in the rviz!
