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).

Asir now uses gc7. In non-ox mode, SIGINT received during GC is recorded in a variable 'in_gc' and int_handler() is executed after GC.

Enhanced the multiplication in Weyl algebra. Added and modified some new functions related to plotting.

A canvas is specified by (Id,Index), where Id is the identifier for an ox server. open_canvas(Id): create a white canvas. draw_obj(Id,Index,PointOrSegment): create a white canvas. This function also pushes the index. PointOrSegment : a list. If the length is 2, it is regarded as a point. If the length is 4, it is regarded as a line segment. clear_canvas(Id,Index): clears the canvas.

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.
