Moving to GitHub!

This should include the most up-to-date software since the end of ME
327. I have saved older drafts to my local machine, just in case. As
you know, there is no need to save dated versions with GitHub. Note
that the “Adding gTec” folder contains modifications of source and
include files from the end of ME 327 (i.e., pre-new hardware) to allow
input from the g.tec g.MOBIlab+ via BCI2000. According to Allison, we
also need to rid all files of the name “NeuroTouch” (since it’s already
taken).
