[ANN] ratfun-2.4 Polynomials and Rational Functions

[Raymond L. Buvel]

The ratfun module provides classes for defining polynomial and rational
function (ratio of two polynomials) objects. These objects can be used
in arithmetic expressions and evaluated at a particular point.

Note: If you are using rpncalc-1.2 or later, this module is already
included.  This release is for folks who don't want rpncalc.

Changes in 2.4

* Updated the included clnum package.

* Added uniqueRoots to handle polynomials with multiple roots.
