Summary description:  A parser for polynomial expressions

Announcement text:

 There are two main changes:

 - polynomials are also made known as functions to the \xintfloatexpr
   parser. This is indispensible for numerical algorithms (such as
   finding roots by Newton's method or Regula Falsi) as exact
   computations quickly give very big fractions.

 - there was a breaking change for \PolToExpr. It now outputs in
   descending powers; use \PolToExpr* for ascending powers.

 See README.md for more.

 The documentation (in polexpr.html) was extended and fully revised.
