/*
* This library aims to read data from Electronic Fuel Injection
* or Engine Control units. It is focused around the generic
* internal combustion engine state message provided by the
* UAVCAN protocol due to its comprehensiveness, but is extensible
* to use other forms of data transfer besides UAVCAN.
*
*
*
* Authors: Sriram Sami and David Ingraham
* With direction from Andrew Tridgell, Robert Lefebvre, Francisco Ferreira and
* Pavel Kirienko.
* Thanks to Yonah, SpektreWorks Inc, and HFE International.
