Below is a simple starter program. Note that this program does not pass any
arguments in the functions. Go to the gdx_getting_started_2.py example to
see how you can pass arguments to the open(), select sensors(), and start()
functions, and avoid the prompts.
**** This example assumes the Go Direct sensor is connected via USB.

if measurements == None:
