float ddist	(	float	x1,
		float	y1,
		float	z1,
		float	x2,
		float	y2,
		float	z2
	)

## FONCTION: float ddist(float x1, float y1, float z1, float x2, float y2, float z2)

## SPECIFICATION: Calculate the square of the euclidian distance between two points in space p1(x1, y1, z2) and p2(x2, y2, z2)

## PARAMETRES: @ float x1, y1, z1: The first point's coordinates. @ float x2, y2, z2: The second point's coordinates.

## RETURN: float: the squared euclidian distance between the two points.
