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).

2. if a*pw+mw[i]>b*pw+mw[j] then
   apply POT if ispot=1 or TOP if ispot=0 with tiebreaker.
length(pw) must be equal to the number of variables.
length(mw) must be equal to the module rank.
