simple script to set up a wifi model and print if packets are received

I'm using a simple point to point wifi setup, with a jakes propagation loss
model between two nodes.  It seems that regardless of the settings I put into
the loss model, the received signal is always either 'nan' or 0.  I have
attached a sample script to show this behavior (logging via the terminal should
be turned on).

I have also found that in the source code for the propagation loss model, if
you add this print statement to the constructor:

    JakesPropagationLossModel::JakesPropagationLossModel ()
    {
        DoConstruct ();    
        printf("osc: %d, ray: %d\n",m_nOscillators,m_nRays);
    }

Both these values won't necessarily be what they should be.  (For me it says
m_nOscillators is 0, and m_nRays is 3, although rays should be 1 and
oscillators should be 4)  Also, in jakes-propagation-loss-model.h (lines
127-128), if the declaration of these two variables are switched.  So instead
of:

            uint8_t m_nRays;    
            uint8_t m_nOscillators;        

they are switched to this:

            uint8_t m_nOscillators;    
            uint8_t m_nRays;    

Then the print statement will switch the values of the variables (so for me
m_nOscillators is 3 and m_nRays is 0).
