+Change naming of MTU and packet size attributes in CSMA and Point-to-Point devices<br>
+After much discussion it was decided that the preferred way to think about 
+the different senses of transmission units and encapsulations was to call the 
+MAC MTU simply MTU and to use the overall packet size as the PHY-level attribute
+of interest.  See the Doxygen of CsmaNetDevice::SetFrameSize and 
+PointToPointNetDevice::SetFrameSize for a detailed description.
