Ptr<RateErrorModel> em = CreateObjectWithAttributes<RateErrorModel> (
"RanVar", RandomVariableValue (UniformVariable (0., 1.)),
"ErrorRate", DoubleValue (0.00001));
Ptr<RateErrorModel> em = CreateObject<RateErrorModel> ();

The above code instantiates a ``RateErrorModel`` Object. Rather than
using the two-step process of instantiating it and then setting Attributes,
we use the convenience function ``CreateObjectWithAttributes`` which
allows us to do both at the same time. We set the "RanVar"
``Attribute`` to a random variable that generates a uniform distribution
from 0 to 1. We also set the "ErrorRate" ``Attribute``.
The above code instantiates a ``RateErrorModel`` Object, and
we set the "ErrorRate" ``Attribute`` to the desired value.
We then set the resulting instantiated ``RateErrorModel`` as the error
model used by the point-to-point ``NetDevice``. This will give us some
retransmissions and make our plot a little more interesting.
