c@135:    This is an example of a library that exports more than one "plugin"
c@135:    from a single C++ class. The VampTestPlugin class is constructed
c@135:    with an argument that determines whether it is a time- or
c@135:    frequency-domain plugin, and the library offers both.
c@135: 
c@135:    Where normally a library that offered two plugins would have two
c@135:    static PiperAdapters specialised with the two plugin classes, here
c@135:    we want two static PiperAdapters specialised with the same class
c@135:    but different constructor arguments. This is one way to do that,
c@135:    taking advantage of the fact that PiperAdapterBase exposes
c@135:    createPlugin as a virtual method.
c@135: 
c@135:    Note that a very similar mechanism is used in the standard Vamp
c@135:    version of this plugin library.
