Summary description: Provides a parser for polynomial expressions

Announcement text:

This LaTeX package provides "\poldef": a parser of polynomial expressions
based upon the "\xintdeffunc" mechanism of package xintexpr.

The syntax is

\poldef <name>(x):=<expression in variable x>;

where in place of "x" an arbitrary letter is authorized. The expression
uses the operations of algebra (including composition of functions) with
standard operators, fractional numbers (possibly in scientific notation)
and previously defined polynomial functions or other constructs as
recognized by the \xintexpr numerical parser.

The so-defined name() \xintexpr-function is also known to the package
via its polynomial coefficients, thus allowing dedicated macros to
implement polynomial algorithmics.
