Create sample ELM-327/OBD-II application

I created an application that uses a bluetooth ELM327 to pull live information from a car, such as engine temp, rpm, speed etc.

I ran this on a Raspberry Pi B with my car, might be a useful sample application for others to build upon.

Application is mentioned here:
