Off-the-Shelf DAQ

Here is the high-level walk-thru of the 'First Demo' tutorial:

Initially. VM comes up and the first time, always start the 'First Demo' tutorial (which amounts to calling an icon on the desktop, that you could always re-run at any point).
[After the first time, user sees popup option for Normal Mode else Wiz mode].
- The script backs of databases and user_data and populates them with tutorial data.
- Starting the tutorial means the emulator starts in background and normal mode is pre-configured to work with emulator.

Step 1. Exercise emulator
- write/read
- stream data
- live historgram vieiwing

Step 2. Run emulator external to VM and exercise again
