Vector

Vector used to describe point on world. Has three float's(x, y and z axis)

Vector.new():

		Creates new Vector object (+inf, +inf, +inf)

Vector.new(float x, float y, float z):

		Creates new Vector object (x, y, z)

float x

		x value of object

float y

		y value of object

float z

		z value of object

float Length()

		Returns Length ( sqrt(x*x + y*y + z*z) )
