Coercion to a 'symbolicQspray' object

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.
