Returns a vector of the cross product of two vectors

Code representation:

local a = vector.new(1, 2, 3)
local b = vector.new(2, 1, 2)

local c = vector.new(
 (a.y * b.z - a.z * b.y), 
 (a.z * b.x - z.x * b.z),
 (a.x * b.y - a.y * b.x))

--c.x = 1
--c.y = 4
--c.z = -3

Code example:

local a = vector.new(1, 2, 3)
local b = vector.new(4, 5, 6)

local c = a:cross(b)

print(c.x)
print(c.y)
print(c.z)
--(-3)
--6
--(-3)
