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.

* The Resource class is a convenient way to track allocated resources.
|
|
* It tracks them as indicies in the range [0 .. elements - 1].
|
|
* E.g. the library uses this to track hardware channel allocation.
|
|
*
|
|
* The Resource class does not allocate the hardware channels or other
|
|
* resources; it just tracks which indices were marked in use by
|
|
* Allocate and not yet freed by Free.
