RECORDINGS EXAMPLE

This script illustrates how basic recordings can be run
via the python API. The following steps are needed for a full
recording:

1. Initialize the recording settings.
2. Prepare the stimulation array (see simulate.py for more
explanation).
3. Define an electrode group for data storage.
4. Begins the recording.
5. Stop the recording and save the file.

For further explanation about specific functions, please have
a look at the API documentation.
