DHT22 temperature and humidity

[FDelporte]

This component to measure temperature and humidity is a "tricky one". It requires very strict timing to get correct results. As it is also a component in the CrowPi, there has already been done quit some experiments to get good results, but at the end both Java and Python didn't deliver very good results and a different approach was chosen with a Linux file.

But in this discussion other approaches are listed with SPI and active polling: Pi4J/pi4j-v2#191

Can a full functional Java implementation for the DHT22 be included in this example project?
