DP object now accepts general data type as coefficients.
Added DPM (element of a free module) and several related functions:
dpm_ltod, dpm_dtol, dpm_ht, dpm_hm, dpm_hc, dpm_nf, dpm_weyl_nf etc.
A monomial of DPM is represented as <<d0,d1,...:k>>, which
represents x0^d0*x1^d1*...*ek (ek is the k-th standard base of k[X]^n).

A trace generating facility for groebner basis computation is being
implemented. 'lib/gr/tracetogen' converts the trace into the generating
coefficients. (Experimental)

Example:

[...] dp_gr_flags(["GenTrace",1,"OXCheck",-1]);
[...] G = dp_gr_main(B,V,0,0,0)$ /*G[0] : gb, G[1] : gbindex, G[2] : trace */
[...] Tr = tracetogen(G[1],G[2])$

Tr is a vector whose i-th element is a vector containing coefficients
of the generation of the i-th intermediate basis element.

Added a function for verification of Groebner basis computation.
Details will be soon informed.

I'm sorry. I have to commit too many modifications at once.

Major modifications are for optimization of modular groebner base computation.

1. F4

	array.c, gr.c (still experimental)

2. Weyl algebra

	dist.c, distm.c : product of monomials (weyl_mul*)
	Q.c : coefficients of the expansion of D^k*x^l (mkwc, mkwcm)

    Note that the current implementation and specification are too ad hoc.

	If ctrl("do_weyl",1) is executed, then all monomial operations are
	done in Weyl algebra. If the length of the exponent of a monomial
	is n=2m, then it is regarded as an element of Q<x1,...,xm,Dx1,...,Dxm>.
	If the length is n=2m+1, then it is a regarded as an element of
	Q[h]<x1,...,xm,Dx1,...,Dxm>, where h is the homogenization variable.
	The order specification is the same as in the commutative case, so
	one should use matrix order to realize natural orderings in Weyl
	algebra. Negative waits have not yet been supported.

Fixed a bug in resf_hensel() which causes SEGV for non-monic inputs.

Experimental implementation of linear equation solving by Hensel
in F4. It works but it is very slow, so currently it is not used.

Fixed a bug in sp around gathering hidden algebraic numbers.
