Suggestion: FourierTransform: <Increase spacing between vector entries>

[jhtullis]

Suggestion:

Currently, this is how the vector displays:
$$w_n^{(k)} = [\omega_n^0 \omega_n^{-k} \cdots \omega_n^{-(n-1)k}]$$

I feel like this is a little cramped and makes it look like a product and not a vector. It might be better to display it like this:
$$w_n^{(k)} = [\omega_n^0 \quad \omega_n^{-k} \quad \cdots \quad \omega_n^{-(n-1)k}]$$
