"""
Test example showing how to use the ihcsdk to connect to the ihc controller
To run the example create a file '.parameters' in this folder and add:
ihcurl username password resourceid
The resourceid is an ihc resource id of any boolean resource in you controller.
The resource will be toggled when the test starts, and after this you can set it
using '1' and '2'. 'q' to quit
