// $Log: AvHResearchManager.cpp,v $
// Revision 1.11  2002/10/24 21:41:15  Flayra
// - Attempt to fix progress bars not showing up in release, or when playing online (can't quite figure out when).  Never safe to compare floats anyways.
//
// Revision 1.10  2002/09/23 22:28:33  Flayra
// - Added GetIsResearching method, so automatic armory resupply could be added
//
// Revision 1.9  2002/08/02 21:50:37  Flayra
// - New research system
//
// Revision 1.8  2002/07/24 19:09:17  Flayra
// - Linux issues
//
// Revision 1.7  2002/07/24 18:45:42  Flayra
// - Linux and scripting changes
//
// Revision 1.6  2002/07/23 17:20:13  Flayra
// - Added hooks for research starting, for distress beacon sound effects
//
// Revision 1.5  2002/05/23 02:33:20  Flayra
// - Post-crash checkin.  Restored @Backup from around 4/16.  Contains changes for last four weeks of development.
