directions (up, down, left, right, forward, backward) for int3 and int2 and one vectors for int2 and int3

[lucid-dreamm]

Main directions for int2 and int3 do not exist in mathematics library, right?
Also, for float3, they are not initialized only once (static) as they are in Vector2 and Vector3
Is there any reason for that?
