PolyRing
Represents a JAS polynomial ring: GenPolynomialRing.
Provides more convenient constructor. Then returns a Ring.
Example of the construction a polynomial ring over the rational
numbers QQ() in the variables 'x' and 'y', together with the input of a
polynomial (x+y)**3. >>> from jas import PolyRing, QQ
>>> r = PolyRing(QQ(),"x,y") globally defined
variables: one, x, y
The example works with p = (x+y)**3, but in doctests the full notation
r.x and r.y must be used for x respectively y. >>> p =
(r.x+r.y)**3 >>> print p ( y**3 + 3 * x * y**2 + 3 * x**2 * y +
x**3 )
