Initial changes for DSC. Configure to use our particular headset, also log values to a file. Crude at the moment, will clean up.
Add logged data points from two sessions. One from about an hour this morning when I was just eating breakfast and doing nonchalant things. Another from last night covering a short time before bed and the first ~90 minutes of sleep (I was dozing but eventually the stupid headset was too annoying so I took it off). Hopefully the latter we can find some beta/sleep waves that differ from the former, but haven't done any analysis yet.
