Function: hgmparams
Section: hypergeometric_motives
C-Name: hgmparams
Prototype: G
Help: hgmparams(H): H being a hypergeometric motive template, returns
 [d, w, [P, T], M], where d is the degree, w the weight,
 P the Hodge polynomial and T the Tate twist number (so that the Hodge
 function itself is P/x^T); finally M is the so-called M-value.
Doc: $H$ being a hypergeometric motive template, returns
 $[d,w,[P,T], M]$, where $d$ is the degree, $w$ the weight,
 $P$ the Hodge polynomial, and $T$ the Tate twist number (so that the Hodge
 function itself is $P/x^{T}$); finally the normalizing factor $M$ is the
 so-called $M$-value, $M = \prod_{n} n^{n\gamma_{n}}$.
