// Class: OperatorPluginManager
//
// Purpose:
// The operator plugin manager. It reads in the operator
// plugins and provides information about the operator plugins.
//
// Programmer: Eric Brugger
// Creation: March 7, 2001
//
// Modifications:
// Jeremy Meredith, Fri May 11 14:09:33 PDT 2001
// Added a PluginCategory which must be passed to Initialize.
// Added an array of handles for the real shared libraries.
//
// Jeremy Meredith, Thu Jul 26 09:32:55 PDT 2001
// Renamed plugin info classes.
//
// Jeremy Meredith, Thu Sep 6 16:23:17 PDT 2001
// Reworked this to support more advanced plugin management, and
// support for runtime plugin loading/unloading.
//
// Brad Whitlock, Thur Jul 12 17:44:54 PST 2001
// Added support for scripting plugins.
//
// Jeremy Meredith, Tue Jan 15 16:12:47 PST 2002
// Added runtime parallel config.
//
// Brad Whitlock, Fri Mar 29 09:21:27 PDT 2002
// Ported to windows.
//
// Jeremy Meredith, Fri Jul 5 17:36:23 PDT 2002
// Made it work on plugins from multiple directories.
//
// Jeremy Meredith, Tue Jul 9 17:42:07 PDT 2002
// Made LoadCommonPluginInfo return a success flag.
//
// Jeremy Meredith, Tue Aug 20 16:57:40 PDT 2002
// Refactored most stuff into common PluginManager base class.
//
// Jeremy Meredith, Fri Feb 28 12:26:45 PST 2003
// Renamed LoadCommonPluginInfo to LoadGeneralPluginInfo to clarify its
// purpose (which really is unrelated to FreeCommonPluginInfo and
// GetCommonPluginInfo).
//
// Brad Whitlock, Tue Jun 24 10:48:11 PDT 2008
// Removed singleton characteristics.
//
// Brad Whitlock, Wed Jun 17 10:24:46 PDT 2009
// I added arguments to Initialize.
//
// Brad Whitlock, Fri Feb 5 14:44:32 PST 2010
// I added stuff to enable categories to be accessed for any plugin whose
// libI was loaded.
