Introduces the symbolicQspray objects. Such an object represents a multivariate polynomial whose coefficients are fractions of multivariate polynomials with rational coefficients. The package allows arithmetic on such polynomials. It is based on the qspray and ratioOfQsprays packages. Some functions for qspray polynomials have their counterpart for symbolicQspray polynomials. A symbolicQspray polynomial should not be seen as a polynomial on the field of fractions of rational polynomials, but should rather be seen as a polynomial with rational coefficients depending on some parameters, symbolically represented, with a dependence given by fractions of rational polynomials.
