// Name:		FollowPathToPoint
// Base Class:	FollowPath
//
// Description:	FollowPathToEntity is a specialization of
// FollowPath used when the Actor must move to a stationary point
//
// Method of Use:	Behaviors Aggregate FollowPath classes to 
//					handle long term motion to a goal

// Name:			SetGoal
// Class:			FollowPathToPoint
//
// Description:		sets goal point and creates a path to it
//
// Parameters:		
//					Vector targetPoint - goal position
//					float radius - how close actor needs to get to goal
//					Actor self - the Actor trying to get to the goal
//
// Returns:			None
