network(), radar() and site() objects

This notebook introduces the high-level python interface with the radar.dat and hdw.dat content.
For more in-depth access (i.e., your own hdw.dat), look at the radInfoIO module:

# Import radar module
from pydarn.radar import *

Import all radars

This could be used to iterate through radars, plot them all on a map, find radars in view of specific points...
