Comment (by ncohen):
> IMHO `hadamard_matrix()` should accept options, such as `RSHCD` and
`skew` (the latter not implemented yet).
HMmmmm.. I don't know for 'skew', but 'rshcd' sounds very very specific to
have in such a general function. Having a function of its own in a
submodule sounds sufficient to me, for the moment.
> As well, `is_hadamard_matrix()` ought to check for `RSHCD`-ness and
`skew`-ness.
I don't know... The rshcd function already tests the rshcd-specific
property anyway.
