Previously, the C++ and C versions of this driver were separate. Now the C++ implementation wraps the C implementation. In addition, the C++ init() function has been deprecated. It currently does nothing, and examples have been modified to remove it's calls. This function will be removed in a separate release. The examples have been further modified to update all detected devices and print their respective temperatures, instead of only reporting the on the first device detected.
