Detailed Description

Provides a way of specifying network transport hints to ros::NodeHandle::subscribe() and someday ros::NodeHandle::advertise().

Uses the named parameter idiom, allowing you to do things like:

ros::TransportHints()
        .unreliable()
        .maxDatagramSize(1000)
        .tcpNoDelay();

Hints for the transport type are used in the order they are specified, i.e. TransportHints().unreliable().reliable() specifies that you would prefer an unreliable transport, followed by a reliable one.
