Some minor modifications have been necessary due to the updates of some package dependencies. No change for the user regarding this point.

New function HallLittlewoodPol, to get a Hall-Littlewood polynomial. A
Hall-Littlewood polynomial is a multivariate symmetric polynomial associated

It is now possible to get a Jack polynomial with a symbolic Jack parameter
in its coefficients. Such polynomials are returned by the function JackSymPol.
This big progress is the reason for which I increased the major component of
the version of the package.
Since the functions implemented with Rcpp are highly more efficient,
the functions Jack, JackPol, Schur, SchurPol, Zonal, ZonalPol,
ZonalQ, ZonalQPol, have been renamed to JackR, JackPolR, SchurR,
SchurPolR, ZonalR, ZonalPolR, ZonalQR, ZonalQPolR, and the functions
JackCPP, JackPolCPP, SchurCPP, SchurPolCPP, ZonalCPP, ZonalPolCPP,
ZonalQCPP, ZonalQPolCPP have been renamed to Jack, JackPol, Schur,
SchurPol, Zonal, ZonalPol, ZonalQ, ZonalQPol.
New function LRmult, to compute the expression of the product of two Schur
polynomials as a linear combination of Schur polynomials, using the
Littlewood-Richardson rule.
New function LRskew, to compute the expression of a skew Schur
polynomial as a linear combination of Schur polynomials, using the
Littlewood-Richardson rule.
Based on LRskew, the new function SkewSchurPol computes the skew Schur
polynomial of a given skew partition.
Actually there are four possible Jack polynomials of a given partition for a
given alpha, denoted by J, C, Q or P (they are the same up to a
normalization constant). It is now possible to get any of them (the previous
versions only allowed to get the J polynomial).
The Julia stuff has been removed.
SchurCPP, JackCPP, ZonalCPP and ZonalQCPP) are not
restricted to rational numbers: they also allow double numbers.SchurCPP, JackCPP, ZonalCPP and ZonalQCPP.Changed C++20 to C++17.
SchurPolCPP, JackPolCPP, ZonalPolCPP and ZonalQPolCPP. It is faster
than the Julia implementation.Now one can use a bigq number for alpha in JackPol, thanks to the
'gmpoly' package, and one can use exact=TRUE with algorithm=DK for
ZonalPol, ZonalQPol and SchurPol.
Now one can get a gmpoly polynomial with Julia.
Jack_julia, to evaluate the polynomials with Julia.Fixed a test of empty partition
Added more checks of parameters validity
Added more unit tests
Improved documentation
