Get serial communication working between two pis #5

Clone and build this project on Tim's pi and try to get them sending simple messages to eachother. This might work wirelessly, but would probably be simpler over serial/

Once you have video library working you should try triggering a video to play on one pi from another.

This is apparently more complicated than I would have guessed. Going with UART TX/RX for communication between arbitrary number of Pis. Not supported by PIGPIO but apparently there are standard C libraries for dealing with this. Just need to make changes to /boot/config.txt

not trivial, but the current setup works!
