/**
 * Wraps C++ classes (ptrs and refs) so that they can be passed around in
 * Objective-C++ programs without generating a lot of useless Objective-C
 * runtime metadata.
 * Use objc_metadata_hider_ptr for ptrs and objc_metadata_hider_ref for refs.
 * Example use:
 * ```
 *   class Foo {
 *     public:
 *       ....
