Definition of Moment

The current state is somewhat confused, it not being clear from
Appendix C whether moment is about 0, or central (i.e. about the mean).
'mean' is said to be the first moment, which can't be true if moments are
about mean.
I see three options.
(a) Define them to be about zero.
    Probably easiest as an edit, but may not be right
(b) Define them to be central.
    Possibly more useful, but means fixing 'mean'
(c) Add a third parameter, meaning "about where".
    Could be helpful, since literature is ambiguous on what a moment is,
