diff: typeclass user documentation

[David Matthew OVERTON]

Hi DJ,

I've got a couple of minor suggestions about your documentation:

> +:- pred distance(P1, P2, float) <= point(P1), point(P2).
> +:- pred distance(in, in, out) is det.

s/pred/mode/ in the 2nd line.

Also, what is the syntax when combining the type and mode declarations
into one declaration (if this is allowed)?

David
