Comment(by jason):
Some more comments after examining things more carefully:
* Use "is not None" rather than "!= None", as the "is not None" is way,
way faster (it's a pointer comparison)
* If I have just a few excluded points, but lots more poles, won't the
break during the calculation of the exclusions also jump out of the loop
that deals with detecting poles? That means my poles past the last
exclusion point are ignored.
* Can you put a brief comment in about {{{(x0 < exclusion_point <= x1 or
x0 <= exclusion_point < x1)}}}? It may be just that it's too late, but
this is confusing me a bit.
Those are the only issues I find; the code other than that works fine. I
have not tested the output (nice doctests, though!).
