class PawnProxyPathing extends PawnProxy;

/*-----------------------------------------------------------------------------
Singleton class used to perform pathing for non-Pawn actors (e.g. projectiles).
Subclasses should set desired properties to use during pathing (e.g. bCanFly
and collision sizes etc.).

Users should be able to do something like (untested):

	class'PawnProxyPathing'.static.FindPathToActor( Self, DestinationActor, TargetActor, bIncludeDirect, bClearPaths, bClearSpecialColliders );

	for( P = ContextActor.Level.PawnList; P != None; P = P.nextPawn )

			return PawnProxyPathing(P);
