Linux sysfs gpio access

This library provides gpio access via the standard linux sysfs interface

It is intended to mimick RPIO as much as possible for all features, while also supporting additional (and better named) functionality to the same methods.

Supported Features

sysfs is still under development, and so only supports minimal features

get pin values with read(pin) or input(pin)
set pin values with set(pin, value) or output(pin)
get the pin mode with mode(pin)
set the pin mode with setup(pin, mode)
- mode can currently equal sysfs.IN or sysfs.OUT

Future Features

setting pullup / pulldown values for pins
setting pins as pwm
