resultant: Utilities for Multivariate Polynomials with Rational Coefficients

Computation of resultant, subresultants, greatest common divisor, integral division (aka division without remainder) of two multivariate polynomials with rational coefficients, Sturm-Habicht sequence and square-free factorization of a multivariate polynomial with rational coefficients. The computations are performed by the 'C++' library 'CGAL' (<https://www.cgal.org/>). Resultants have applications in polynomial systems solving, number theory, and algebraic geometry. The package also contains some functions computing the number of real roots of a univariate polynomial with rational coefficients, and a function computing the division with remainder of two univariate polynomials with rational coefficients.
