* "Pimpl idiom" (pointer to implementation idiom).
* The OSMOSDR_PIMPL_* macros simplify code overhead for declaring and making pimpls.
*
* Each pimpl is implemented as a shared pointer to the implementation:
* - The container class will not have to deallocate the pimpl.
* - The container class will use the pimpl as a regular pointer.
* - Usage: _impl->method(arg0, arg1)
* - Usage: _impl->member = value;
*
* \see http://en.wikipedia.org/wiki/Opaque_pointer
