This is the changes made by Patrick Plenefisch converting the native code to use CMake and the CMake Maven Plugin, as opposed to the native Maven plugin. This is to allow for compatibility with newer versions of the GCC toolchain. All the cpp sources were moved from maven style directories to cpp style directories for CMake.

* There is a 64-bit hardware accumulator associated with channel 1 on each module.

* The accumulator is attached to the output of the oversample and average engine so that the center
