RTCP statistics class.

The class stores following RTCP statistics for the current RTP session

1. Cumulative number of packet sent since 
   the RTP session started until current SR report is generated
2. Number of payload octets sent since the RTP session started until 
   current SR report is generated
3. Inter arrival jitter 
4. Cumulative number of packet lost since the beginning of reception 
5. Fraction of packets lost current active RTP session since the previous 
   RR packet was sent
