// Purpose: Implementation of entities that cause NPCs to participate in
// scripted events. These entities find and temporarily possess NPCs
// within a given search radius.
//
// Multiple scripts with the same targetname will start frame-synchronized.
//
// Scripts will find available NPCs by name or class name and grab them
// to play the script. If the NPC is already playing a script, the
// new script may enqueue itself unless there is already a non critical
// script in the queue.
