After looking at the ridgedmf and heteromf  sections (I guess I never
actually looked at them in 'published form' before), there are at least
a couple of errors. It should not give the impression that the
correct syntax is f(x,0,z). That syntax can be used  to enforce
a height field like surface, but the multifractals can be used nicely
for many other types of surfaces (clouds, planets, thingamablobs, etc)
Another error in the docs is where the -H is supposed to
be an exponent on f, not subtracted from f. (probably html superscript
got lost somewhere)
