Assume you have sequence xi, yi, zi, where yi and zi are function values
corresponding to xi. In general, you will never have exact intersection
with yi==zi. So in addition, look for successive triples xi,yi,zi and
x(i+1), y(i+1), z(i+1) such that yi<zi and y(i+1)>z(i+1) or the other way
around. In other words, zi-yi and z(i+1)-y(i+1) have opposite signs. You
might want to also consider abs(zi-yi) < some very small number as possibly
indicating touching without crossing (as with tangents).
