ahvec_abc(A,B,C,X|all=1) evaluates normalizing constant (zero row or column are allowed).
Example:
ahvec_abc(-6,[-3,-4],-4,[[1,1/2,1/3],[1,1,1]] | all=1);

ahvec_beta(Beta,X | all=1) returns the normalizing constant and its derivatives.
It evaluates the NC when a row sum is zero or column sums are zero as well as marginal sums
are non-degerated.

Example: fvect_poly2(-5,[-4,-3],-2,[1/2,1/3]);
fvect_poly2 utilizes contiguity relation for c->c-1, a->a-1
and evaluates hg polynomial when c <= 0.
fvect_poly and ahvec call this function when c<=0.

Added functions to evaluate F_D like polynomials when c is a negative integer.
hgpoly_fd(A,B,C) returns [a polynomial, distributed form, variables].
atofd(F,A,B,C,Z) returns a polynomial satisfying F_D eq from hgpoly.
ygDk(X,K,A,B,C)/(-B[K-1]+1) (perhaps) gives a step down operator with respect
to b_k = B[K-1].  cf. check23().

The option all is added to ygahvec (see the usage of ahvec).
New functions: marginal2abc and abc2marginal.

The option all is added to ahvec.
When F is the return value of ahvec, then F[2]*F[1] is the value of
hypergeometric polynomial.

tk_fd.dx(1) retuns tk_fd.dx_1 (bug or specification).
The function name dx is changed to dxx to avoid this.
yg*() are implementations of Y.Goto's difference relation, which is a work in progress.
