Remove wait_for_input, add_callback and remove_callback from the base InputDevice class and add specific things for LightSensor: wait_for_light and wait_for_dark to wait on those events occurring, and when_light and when_dark which can be set to callbacks to call on those events occurring.

gpiozero
========
A simple interface to everyday GPIO components used with Raspberry Pi
*A work in progress*
Motivation
==========
The "hello world" program in Java is at least 5 lines long, and contains 11
jargon words which students are taught to ignore.
The "hello world" program in Python is one simple line. However, the "hello
world" of physical computing in Python (flashing an LED) is similar to the Java
program: 6 lines of code to flash an LED.
Young children and beginners shouldn't need to sit and copy out several lines
of text they're told to ignore. They should be able to read their code and
understand what it means.
Install
=======
Install with pip::
sudo pip install gpiozero
sudo pip-3.2 install gpiozero
Usage
=====
Example usage for flashing an LED::
from gpiozero import LED
from time import sleep
led = LED(2)
while True:
led.on()
sleep(1)
led.off()
sleep(1)
