updated run_me_for_demo to use Bluetooth
added maryland talk stuff and new pictures

I have pictures of the new board, the new glasses and the stonyman
breakout.  The pictures in the maryland-talk folder (excluding the
diagrams I made) are from around the web, mostly from wikimedia commons.
moved the SensEye architecture diagram

into a folder 'media/diagrams'
started a figure which details computing classes

The classes are currently "8- and 16-bit MCUs", "32-bit MCUs",
"Cell-phone class MCUs/CPUs", "CPUs" and "Specialty" where specialty
contains DSPs and perhaps oddities like the Parallax chips.
changed the performance metric to CPI

it was FLOPS before, but I just had quickly jotted that in without
thinking.  Really the metric needs to be some combination of frequency
and CPI.
added two 3.3V masks for camera 3

computed with the teensy platform, not the smartfusion platform
power spreadsheet updated to compute BT power
changed power spreadsheet format to MS Office 1997
created a stonyman FPS calculations spreadsheet
