#11764: define the class MPolynomial at the top-level

-----------------------------------+----------------------------------------
for univariate polynomials we have the class {{{Polynomial}}}:
{{{
sage: R.<x> = QQ[]
sage: isinstance(x+1, Polynomial)
True
}}}
However for multivariate polynomials we have to write:
{{{
sage: R.<x,y> = QQ[]
sage: isinstance(x+y, sage.rings.polynomial.multi_polynomial.MPolynomial)
True
}}}
I suggest {{{MPolynomial}}} is defined as an alias for
{{{sage.rings.polynomial.multi_polynomial.MPolynomial}}} so that we can
simply write:
{{{
sage: R.<x,y> = QQ[]
sage: isinstance(x+y, MPolynomial)
True
}}}
