How to Enable PyViz Visualizer

[Kavya Bhat]

Hi Amruth,

Based on the configuration summary, it looks like the Python bindings are off. You'd need to enable this in order to use the PyViz visualizer.

Adding `--enable-python-bindings` to your command (entire line: `/usr/bin/python3 ns3 configure --enable-python-bindings`) should enable the bindings and also the visualizer. 

Hope this helps!
