* PluginAdapter and PluginAdapterBase provide a wrapper class that a
* plugin library can use to make its C++ Vamp::Plugin objects
* available through the Vamp C API.
*
* Almost all Vamp plugin libraries will want to make use of this. To
* do so, all they need to do is declare a PluginAdapter<T> for each
* plugin class T in their library. It's very simple, and you need to
* know absolutely nothing about how it works in order to use it.
* Just cut and paste from an existing plugin's discovery function.
