// identity is now a 2-D Array

// points are 1-D arrays

// let's create a stupid simple 3D perpendicular frame
frame = identity

// singular values
hang = l.transpose(identity)
stretch = identity
align = identity

// cook up a matrix that does nothing
A = l.dot(hang, stretch, align)

// make sure it actually does nothing
assert.deepEqual(l.dot(A, point), point)
