 * \class PluginStaticData
 * 
 * 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 Vamp::Plugin class itself); this structure
 * just pulls it together in one place and provides something that can
 * be stored and recalled without having a Vamp::Plugin object to
 * hand.
