Emulation of GPIO

[mikebaldry]

It'd be nice to be able to build this on other operating systems, and have it simply emulate GPIO.

For instance, you could set direction/value and read back from it.

This would allow us to run unit tests against code using GPIO without being on a raspberry pi or having GPIO pins :)

I would love this, too! I'm thinking it would be swell to have some kind of Mock-ing mechanism. :D If I can help, I'm happy to. I have a project starting now that would be ideal for my working on code in rpi_gpio to help make testing "easier".
