Detailed Description

implements the Mean-Deviation RTT estimator

reference: ns3::RttMeanDeviation

This RttEstimator algorithm is designed for TCP, which is a continuous stream. NDN Interest-Data traffic is not always a continuous stream, so NDN may need a different RttEstimator. The design of a more suitable RttEstimator is a research question.
