[Numpy-discussion] polynomial package update

[Charles R Harris]

Hi All,

I've made a pull request for a  rather large update of the polynomial
package. The new features are

1) Bug fixes
2) Improved documentation in the numpy reference
3) Preliminary support for multi-dimensional coefficient arrays
4) Support for NA in the fitting routines
5) Improved testing and test coverage
6) Gauss quadrature
7) Weight functions
8) (Mostly) Symmetrized companion matrices
9) Add cast and basis as static functions of convenience classes
10) Remove deprecated import from package *init*.py

If anyone has an interest in that package, please take some time and review
it here <https://github.com/numpy/numpy/pull/181>.

Chuck
