//
// 30 10/26/98 4:27p Jimdose
// Sped up ValidEvent
// Added FindEvent( const char * )
//
// 29 10/25/98 11:53p Jimdose
// added EXPORT_TEMPLATE
//
// 28 10/18/98 8:45p Jimdose
// changed commandList to a str * container
//
// 27 10/18/98 3:21a Jimdose
// made the assert in getName only fire if eventnum is non-zero
//
// 26 10/17/98 11:33p Jimdose
// Added the event name to Event to help with debugging
//
// 25 10/08/98 12:39a Jimdose
// Added event archiving functions
//
// 24 9/25/98 4:41p Markd
// Changed Find functions to return an Event rather than a &Event, made the
// Exists function
//
// 23 9/24/98 1:45a Jimdose
// Made Event a subclass of Class
//
// 22 9/19/98 4:33p Jimdose
// Added ListCommands and EV_HIDE
//
// 21 9/02/98 7:48p Aldie
// Moved template around
//
// 20 8/27/98 9:04p Jimdose
// Moved a lot of small functions to the header as inline
//
// 19 8/01/98 7:58p Jimdose
// Fixed bug with cheats in dm
//
// 18 7/31/98 8:10p Jimdose
// Script commands now include flags to indicate cheats and console commands
//
// 17 7/31/98 4:19p Jimdose

//
// 16 7/20/98 5:08p Jimdose
// Added ProcessPendingEvents
//
// 15 7/10/98 10:00p Jimdose
// Made remove script command post remove event so that it doesn't cause
// problems during event callbacks which trigger the script
//
// 14 6/30/98 6:05p Jimdose
// Added IsVectorAt, IsEntityAt, and IsNumericAt for doing type checking on
// args
// Changed format for storing vectors to make it easy to identify
//
// 13 6/27/98 9:18p Jimdose
// Made lookup for event responses for faster processing
//
// 12 6/18/98 8:48p Jimdose

// Added source info to events
//
// 11 5/24/98 8:46p Jimdose
// Made a lot of functions more str-friendly.
