/*
   This is an example of a library that exports more than one "plugin"
   from a single C++ class. The VampTestPlugin class is constructed
   with an argument that determines whether it is a time- or
   frequency-domain plugin, and the library offers both.

   Where normally a library that offered two plugins would have two
   static PiperAdapters specialised with the two plugin classes, here
   we want two static PiperAdapters specialised with the same class
   but different constructor arguments. This is one way to do that,
   taking advantage of the fact that PiperAdapterBase exposes
   createPlugin as a virtual method.

   Note that a very similar mechanism is used in the standard Vamp
   version of this plugin library.
