Robust Rate Adaptation Algorithm.
This is an implementation of RRAA as described in "Robust rate adaptation for 802.11 wireless networks" by "Starsky H. Y. Wong", "Hao Yang", "Songwu Lu", and, "Vaduvur Bharghavan" published in Mobicom 06.
This RAA does not support HT modes and will error exit if the user tries to configure this RAA with a Wi-Fi MAC that supports 802.11n or higher.
ns3::RraaWifiManager is accessible through the following paths with Config::Set and Config::Connect:
Size of this type is 504 bytes (on a 64-bit architecture).

Initialize() implementation.
This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.
Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.
Reimplemented from ns3::Object.
