/**
* This helper method can be used to configure the stream number for
* one or more RNG streams. The path passed in should correspond to
* an attribute path in the configuration system. It may contain wildcards
* and may ultimately match zero, one, or more than one object.
*
* The objects to match are of type PointerValue where the underlying
* type is of type Ptr<RandomVariableStream>.
*
* \code
* .AddAttribute ("Speed",
* "A random variable used to pick the speed of a random waypoint model.",

* MakePointerAccessor (&RandomWaypointMobilityModel::m_speed),
* MakePointerChecker<RandomVariableStream> ())
*
* \endcode
*
* Usage would look (for node 3) like this:
* \code
* std::string path ("/$ns3::NodeListPriv/NodeList/3/$ns3::Node/$ns3::RandomWaypointMobilityModel/Speed/$ns3::UniformRandomVariable");
* int64_t retVal = RandomVariableStreamHelper::AssignStreams (path, 0);
* \endcode
*
* \return The number of streams set
* \param path (possibly wildcarded) path to a RandomVariableStream PointerValue
* \param stream stream number to set; must be non-negative
