Table foosball control library

This library can control our foosball table, which is equiped with:

1. Vibration sensor to detect if anyone is playing

2. Goalsensors based on lasers, which detect goals for each team

3. Scoreboards with 7-segment LED displays to show current score

4. 4x20 character display

5. Raspberry Pi to control the above and host a webpage to show table status

The table is controlled by a Raspberry Pi with the pigpio library (http://abyz.co.uk/rpi/pigpio/). The table detects when people are playing at the table and then turns on the scoreboards, the goal detectors and sets the table occupied, so other people can see on the homepage, that the table is occupied, how long it has been occupied and what the score is.

Match results are (soon) logged, and the plan is, that results, history and statistics can be seen on the homepage and also on the display on the table. A webpage is part of the system, and this library manipulates and reads a few files in /var/www/.

Final step should be to add an RFID reader to the table, so players can scan their id cards or tokens, so the table knows who plays. It can then automatically store the results and update our internal ranking system.

Library elements:

foosball_main.py Main program, which imports everything else and starts everything up
activity.py Separate thread, which just waits for change on activity gpio
goaldetect.py Controls the laser goal detectors
teamscore.py Controls the team scoreboards (and the up/down buttons)
external.py Library to external communication. Read/writes files, recieves signals
matchlog.py Logs all matches played and generel table statistics (in development)
button.py Library to control pushbuttons
max7219bb.py Library to bit-bang the 7219 LED display driver (1 in each scoreboard)
