 * \class PluginStaticData PluginStaticData.h <vamp-hostsdk/PluginStaticData.h>
 * 
 * Vamp::HostExt::PluginStaticData is a structure bundling together
 * all the information about a plugin that cannot be changed by the
 * plugin after it is loaded. That is, everything that does not depend
 * on a parameter or initialisation setting.
 *
 * All of the information in here can be queried from other sources
 * directly (notably the Plugin class itself); this structure just
 * pulls it together in one place and provides something that can be
 * stored and recalled without having a Plugin object to hand.
 *
 * \note This class was introduced in version 2.7 of the Vamp plugin
 * SDK and is used only by host SDK functions that were also
 * introduced in that release (or newer).
