Display subclass using a tf::MessageFilter, templated on the ROS message type.
This class brings together some common things used in many Display types. It has a tf::MessageFilter to filter incoming messages, and it handles subscribing and unsubscribing when the display is enabled or disabled. It also has an Ogre::SceneNode which
