MediumCanvasVisualizer

simple module

This module visualizes a medium on a 2D canvas. It displays communication ranges and interference ranges as circles around network nodes. It displays an image at network nodes which are currently transmitting, and a different image at other network nodes whcih are currently receiving. It also displays radio signals as a 2D ring or a 3D sphere as they propagate through the medium.
