Sounds reasonable. I'd also like to add some features to the polynomial

   1. Improved zero finding with Gaussian quadrature. With the improved
   zeros and using an expression for Gaussian weights things work well up to
   degree 100.
   2. Small change to the evaluation functions adding a "tensor" keyword
   and allowing arrays of coefficients. This change allows easy evaluation of
   tensor products of the polynomials, either on a grid or on a set of points,
   which is handy for working in two or three dimensions.

I think the recent fixes for user types should also go in, but I'd like
Mark to review them first. The R like sampling function could also go in, I
just had a question about the name 'choice', but if that is an R compatible
name I'm OK with it. In fact, I think many of the current pull requests
could go in with the addition of a few tests in some cases. I'll fix the
ma.polyfit function test sometime this week. Maybe we should have a weekend
devoted to getting the current request in.
